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 16:36

16:36 (Now an omer is one tenth of an ephah.) ² 

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

[16:36]  ² tn The words “omer” and “ephah” are transliterated Hebrew words. The omer is mentioned only in this passage. (It is different from a “homer” [cf. Ezek 45:11-14].) An ephah was a dry measure whose capacity is uncertain: “Quotations given for the ephah vary from ca. 45 to 20 liters” (C. Houtman, Exodus, 2:340-41).
