Hath met with us, i.e. hath appeared to us lately, and laid this command upon us. Others, is called upon us, i.e. his name is called upon us, or we are called by his name. But why should Moses so solemnly tell that to Pharaoh which all the people knew, to wit, that the Hebrews did worship the God of the Hebrews? And our translation is confirmed by comparing this with Exodus 3:18, where this very message is prescribed. Lest he fall upon us; lest he punish, either us, if we disobey his command, or thee, if thou hinderest us from obeying it: but this latter they only imply, as being easily gathered from the former.
