Numbers 28:5 is the accompanying grain offering of fine flour and oil prescribed for the daily lamb.

Exodus 29:38-42 institutes the daily offering with the same grain offering recipe—a tenth ephah flour mixed with quarter hin oil.

Exodus 29:40 directly matches the grain offering for the daily lamb: tenth ephah flour and quarter hin oil.

Ezekiel 46:14 prescribes a daily grain offering but with different amounts—sixth ephah flour and third hin oil—reflecting later practice.

Exodus 16:36 defines an omer as a tenth of an ephah, the exact unit used for the flour in Numbers 28:5.

Leviticus 2:1 gives general grain offering rules with fine flour and oil; Numbers 28:5 applies a specific measure for daily offerings.
