Matthew Henry Commentary Exodus 4:24-31

"And it came to pass on the way at the lodging-place, that Jehovah met him, and sought to kill him. Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, Surely a bridegroom of blood art thou to me. So he let him alone. Then she said, A bridegroom of blood [art thou], because of the circumcision. And Jehovah said to Aaron, Go into the wilderness to meet Moses. And he went, and met him in the mountain of God, and kissed him. And Moses told Aaron all the words of Jehovah wherewith he had sent him, and all the signs wherewith he had charged him. And Moses and Aaron went and gathered together all the elders of the children of Israel: and Aaron spake all the words which Jehovah had spoken unto Moses, and did the signs in the sight of the people. And the people believed: and when they heard that Jehovah had visited the children of Israel, and that he had seen their affliction, then they bowed their heads and worshipped." — Exodus 4:24-31 (ASV)

God met Moses in anger. The Lord threatened him with death or sent sickness upon him, as punishment for having neglected to circumcise his son. When God reveals to us what is wrong in our lives, we must make every effort to correct it quickly. This is the voice of every rod; it calls us to return to Him who strikes us.

God sent Aaron to meet Moses. The more they saw of God's bringing them together, the more pleasant their meeting was. The elders of Israel met them in faith and were ready to obey them. It often happens that less difficulty is encountered than was expected in undertakings that are according to God's will and for his glory.

Let us simply arise and attempt our proper work; the Lord will be with us and prosper us. If Israel welcomed the news of their deliverance and worshipped the Lord, how should we welcome the good news of redemption, embrace it in faith, and adore the Redeemer!
