Exodus 16:18

16:18 When ¹  they measured with an omer, the one who gathered much had nothing left over, and the one who gathered little lacked nothing; each one had gathered what he could eat.

Exodus 16:21

16:21 So they gathered it each morning, ²  each person according to what he could eat, and when the sun got hot, it would melt. ³ 

[16:18]  ¹ tn The preterite with the vav (ו) consecutive is subordinated here as a temporal clause.

[16:21]  ² tn Heb “morning by morning.” This is an example of the repetition of words to express the distributive sense; here the meaning is “every morning” (see GKC 388 §121.c).

[16:21]  ³ tn The perfect tenses here with vav (ו) consecutives have the frequentative sense; they function in a protasis-apodosis relationship (GKC 494 §159.g).
