Exodus 34:34

But when Moses went in ¹  before the Lord to speak with him, he would remove the veil until he came out. ²  Then he would come out and tell the Israelites what he had been commanded. ³ 

2Co 3:16; Heb 4:16; Heb 10:19-22

¹ tn The construction uses a infinitive construct for the temporal clause; it is prefixed with the temporal preposition: “and in the going in of Moses.”

² tn The temporal clause begins with the temporal preposition “until,” followed by an infinitive construct with the suffixed subjective genitive.

³ tn The form is the Pual imperfect, but since the context demands a past tense here, in fact a past perfect tense, this is probably an old preterite form without a vav consecutive.
