Exodus 16:32-35

(32-35) And Moses said... Fill an omer. — This narrative, which must belong to a later date than any other part of Exodus, since it assumes that the Tabernacle is set up (Exodus 16:34), seems to have been placed here on account of its subject-matter. The writer wishes to conclude the history of the manna, and has two further points to note concerning it: (1) the preservation of an omer of it as a perpetual memorial (Exodus 16:32); and (2) the fact of its continuance until the Israelites reached the borders of Canaan. The passage is probably an addition to the original “Book,” but contains nothing that may not have been written by Moses.
