tn The word “journey” is an adverbial accusative telling the distance that Moses wanted the people to go. It is qualified by “three days.” It is not saying that they will be gone three days, but that they will go a distance that will take three days to cover (see Gen 31:22–23; Num 10:33; 33:8).

tn The purpose clause here is formed with a second cohortative joined with a vav (ו): “let us go … and let us sacrifice.” The purpose of the going was to sacrifice.

sn Where did Moses get the idea that they should have a pilgrim feast and make sacrifices? God had only said they would serve Him in that mountain. In the OT the pilgrim feasts to the sanctuary three times a year incorporated the ideas of serving the Lord and keeping the commands. So the words here use the more general idea of appearing before their God. They would go to the desert because there was no homeland yet. Moses later spoke of the journey as necessary to avoid offending Egyptian sensibilities (8:25–26).

sn The last clause of this verse is rather unexpected here: “lest he meet [afflict] us with pestilence or sword.” To fail to comply with the summons of one’s God was to invite such calamities. The Law would later incorporate many such things as the curses for disobedience. Moses is indicating to Pharaoh that there is more reason to fear Yahweh than Pharaoh.
