Then Moses and Aaron fell on their faces
Through shame and confusion of face for them, at hearing so shocking a proposal made, and such wretched ingratitude expressed; they blushed at it, and were in the utmost distress on account of it, and therefore threw themselves into this posture; or it may be this was done either to beg of them that they would lay aside all thoughts of this kind, or to supplicate the divine Majesty that he would convince them of their sin and folly, and give them repentance for it and forgiveness of it; and this they did
before all the assembly of the congregation of the children of Israel;
to affect them the more with a sense of their sin and danger.
