¹ Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married, for he had married a Cushite woman. ² And they said, “Has the Lord indeed spoken only through Moses? Has he not spoken through us also?” And the Lord heard it. ³ Now the man Moses was very meek, more than all people who were on the face of the earth. ⁴ And suddenly the Lord said to Moses and to Aaron and Miriam, “Come out, you three, to the tent of meeting.” And the three of them came out. ⁵ And the Lord came down in a pillar of cloud and stood at the entrance of the tent and called Aaron and Miriam, and they both came forward. ⁶ And he said, “Hear my words: If there is a prophet among you, I the Lord make myself known to him in a vision; I speak with him in a dream. ⁷ Not so with my servant Moses. He is faithful in all my house. ⁸ With him I speak mouth to mouth, clearly, and not in riddles, and he beholds the form of the Lord. Why then were you not afraid to speak against my servant Moses?” ⁹ And the anger of the Lord was kindled against them, and he departed.

¹⁰ When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned toward Miriam, and behold, she was leprous. ¹¹ And Aaron said to Moses, “Oh, my lord, do not punish us because we have done foolishly and have sinned. ¹² Let her not be as one dead, whose flesh is half eaten away when he comes out of his mother’s womb.” ¹³ And Moses cried to the Lord, “O God, please heal her—please.” ¹⁴ But the Lord said to Moses, “If her father had but spit in her face, should she not be shamed seven days? Let her be shut outside the camp seven days, and after that she may be brought in again.” ¹⁵ So Miriam was shut outside the camp seven days, and the people did not set out on the march till Miriam was brought in again. ¹⁶ After that the people set out from Hazeroth, and camped in the wilderness of Paran. – Numbers 12:1-16 ESV

Moses was the God-appointed leader of the nation Israel and Aaron, his brother, had been set apart by God to serve as the high priest. Even when God had agreed to provide His chosen leader with administrative assistance, God poured out His Spirit on 70 men who would serve directly under Moses. They were not to replace him or to assume that they served on an equal standing with him. These men were to assist Moses in his oversight of the nation, wisely administering justice and handling disputes among the people so that Moses would not become overwhelmed.

Yet, this chapter introduces a new form of leadership struggle that manifested itself among the people and it started with those who were closest to Moses – his own family. It seems that his brother and sister took issue with a marriage arrangement he had agreed to with a Cushite woman. There is some debate as to the identity of this woman, but it would appear that she was a foreigner of Ethiopian descent. It could be that Moses’ first wife, Zipporah, had died sometime during the last year, and he then chose a new wife. But whatever the circumstances, Miriam and Aaron took issue with the marriage and used it as an excuse to question Moses’ qualifications to lead the nation.

They saw the marriage as evidence of Moses’ lack of discernment and questioned whether he was really hearing from God. In fact, they claimed to be on an equal standing with Moses when it came to divine insight.

“Has the Lord spoken only through Moses? Hasn’t he spoken through us, too?” – Numbers 12:2 NLT

Miriam was older than Moses and had been the one who helped secure his safety when Pharaoh had ordered the murder of all the male babies born among the Israelites living in Egypt (Exodus 1:15-16). She had arranged with the daughter of Pharaoh to have the infant, Moses, nursed by one of the Hebrew women, who just happened to be her own mother (Exodus 2:7-9). Exodus 15:20 refers to Miriam as a prophetess of God, and Micah 6:4 lists her as one of the three individuals whom God appointed to lead the nation of Israel from Egypt to the land of Canaan.

“For I brought you up from the land of Egypt
    and redeemed you from the house of slavery,
and I sent before you Moses,
    Aaron, and Miriam.” – Micah 6:4 ESV

But in Numbers 12, Miriam attempts to convince her brother, Aaron, to join her in staging a coup against Moses. It seems rather odd that she would target Aaron for participation in this little insurrection because he was already second-in-command and served as the high priest of the people. Even before Moses had successfully led the people of Israel out of Egypt, Aaron had served as his administrative assistant. God had appointed him as Moses’ mouthpiece.

“What about your brother, Aaron the Levite? I know he speaks well. And look! He is on his way to meet you now. He will be delighted to see you. Talk to him, and put the words in his mouth. I will be with both of you as you speak, and I will instruct you both in what to do. Aaron will be your spokesman to the people. He will be your mouthpiece, and you will stand in the place of God for him, telling him what to say.” – Exodus 4:14-16 NLT

But Miriam and Aaron had decided that they were just as qualified as their brother to serve as the de facto leaders of Israel. After all, they too had been born into the tribe of Levi and had every right to serve in a leadership capacity. And it didn’t help that Moses was a very humble individual who had no desire for the limelight. Of his own admission, he was far from charismatic or overly eloquent.

“O Lord, I’m not very good with words. I never have been, and I’m not now, even though you have spoken to me. I get tongue-tied, and my words get tangled.” – Exodus 4:10 NLT

His lack of self-esteem made him an easy target for Miriam’s attacks. She believed that Moses had been a poor choice by God and that the Cushite marriage agreement had proven Moses’ lack of discernment. But God disagreed with their assessment and ordered the three siblings to meet Him at the tent of meeting, located just outside the camp. Like three children called out by an unhappy parent, the quarreling siblings did as God said.

And the Lord came down in a pillar of cloud and stood at the entrance of the tent and called Aaron and Miriam, and they both came forward. And he said, “Hear my words…” – Numbers 12:5-6 ESV

Unable to settle their disagreement, God stepped in and, by the time He was finished, Miriam and Aaron would wish they had never opened their mouths against Moses. The first thing God cleared up was His divine right to choose whomever He wanted as His leader. Miriam may have been a prophetess of God, but that did not put her on equal footing with Moses. In fact, God seems to be taking a dig at Miriam’s prophetess status when He states, “If there were prophets among you, I, the Lord, would reveal myself in visions. I would speak to them in dreams” (Numbers 12:6 NLT).

Miriam had experienced no dreams or visions from God. Her demand for equal status was a figment of her own overactive imagination and over-inflated sense of self-worth. And to make sure she understood the vast difference between His relationship with her and the one He shared with Moses, God declared:

“Of all my house, he is the one I trust. I speak to him face to face, clearly, and not in riddles! He sees the Lord as he is.” – Numbers 12:7-8 NLT

That had to have hit Miriam like a brick to the forehead. God’s words stung and burst the bubble of her own sense of self-importance. And, to make matters worse, God demanded to know why she had shown no fear to criticize Moses. Who did she think she was?

Having stated His case against Miriam and Aaron, God departed from them. But He left an unsettling reminder of His displeasure. When Aaron turned to look at Miriam, he was shocked to discover that her entire body was covered with leprosy. Fearing that he was next, he called out to Moses to intervene on their behalf.

“Oh, my master! Please don’t punish us for this sin we have so foolishly committed.” – Numbers 12:11 NLT

The sudden and unexpected sight of his sister covered with a deadly disease must have reminded Aaron of another occasion when something similar had happened to Moses. Back when God had called Moses to be the chosen deliverer of the people of Israel, He had given him a series of signs that were intended to prove to the people of Israel that Yahweh had sent him.

“Put your hand inside your cloak.” And he put his hand inside his cloak, and when he took it out, behold, his hand was leprous like snow. Then God said, “Put your hand back inside your cloak.” So he put his hand back inside his cloak, and when he took it out, behold, it was restored like the rest of his flesh. – Exodus 4:6-7 ESV

Now, more than a year later, Moses and Aaron were staring at their sister, Miriam, whose entire body was covered with this hideous disease. But this time, there was no quick fix. Moses shared his brother’s dismay and desperately pleaded with God for her immediate healing.

“O God, please heal her—please.” – Numbers 12:13 ESV

But God refused to grant his request. Instead, He graciously announced that her punishment would not match the gravity of her crime.

“If her father had done nothing more than spit in her face, wouldn’t she be defiled for seven days? So keep her outside the camp for seven days, and after that she may be accepted back.” – Numbers 12:14 NLT

In essence, God is declaring that Miriam had defiled herself through her actions. And while God could have left her to suffer from the hideous effects of leprosy for a lifetime, He mercifully restricted her period of suffering to only seven days. Yet she would be required to spend the entire time on the outskirts of the camp, suffering the indignity of the disease and the social stigmatization of ceremonial impurity. She was to be treated as unclean and unwelcome among the people of God – until the seven days had passed and He healed her. During the seven days of her punishment, the entire nation of Israel was forced to delay their journey to the land of promise.

Everything came to a halt because Miriam had decided to question the will of God and the authority of His chosen leader. This painful punishment from God should have served as a powerful reminder to the entire nation that no one was immune to God’s discipline against disobedience. Even the sister of Moses.
