tn S. R. Driver (Exodus, 351) draws on Arabic to show that the meaning of this verb (חָלָה, khalah) was properly “make sweet the face” or “stroke the face”; so here “to entreat, seek to conciliate.” In this prayer, Driver adds, Moses urges four motives for mercy: 1) Israel is Yahweh’s people, 2) Israel’s deliverance has demanded great power, 3) the Egyptians would mock if the people now perished, and 4) the oath God made to the fathers.
