Before he left, Moses took Aaron and his son, Eleazar, and went up the mountain and took the special clothes Aaron wore in serving God off of Aaron and put them on Eleazar, showing the people that Eleazer was now God’s high priest. He would be closest to God in God’s house and stand in for the people before God.
After that, the children of Israel started complaining again about their angel bread that God gave them from heaven each morning. God got angry and sent fiery snakes into the camp to bite the complainers. The people said, We have sinned, we have talked bad about the Lord and you Moses. Please pray for us.
