11 This action of Moses and Aaron is typical of them in the wilderness with the Israelites. The act shows self-abasement and deference before the sovereign Lord. They are not bowing before the people here, but in front of the people they bow before God. According to Num 17:6–13 this prostration is for the purpose of intercessory prayer. Here it prevents immediate wrath from God.
12 Heb “before all the assembly of the congregation.”
