Exodus 3:21

3:21 “I will grant this people favor with ¹  the Egyptians, so that when ²  you depart you will not leave empty-handed.

Exodus 33:17

33:17 The Lord said to Moses, “I will do this thing also that you have requested, for you have found favor in my sight, and I know ³  you by name.”

[3:21]  ¹ tn Heb “in the eyes of.” This idiom usually means that someone will be treated well by the observer. It is unlikely that it means here that the Egyptians will like the Hebrews. Rather, it means that the Egyptians will give things to the Hebrews free – gratis (see 12:35-36). Not only will God do mighty works to make the king yield, but also he will work in the minds of the Egyptian people so that they will be favorably disposed to give Israel wealth.

[3:21]  ² tn The temporal indicator (here future) with the particle ki (וְהָיָה כִּי, vÿhaya ki) introduces a temporal clause.

[33:17]  ³ tn The verb in this place is a preterite with the vav (ו) consecutive, judging from the pointing. It then follows in sequence the verb “you have found favor,” meaning you stand in that favor, and so it means “I have known you” and still do (equal to the present perfect). The emphasis, however, is on the results of the action, and so “I know you.”
