Numbers 15:4

A meat offering of a tenth deal of flour... — The meal offering and the drink offering which are here ordered to be brought when a lamb was offered in performance of a vow, or as a free will offering, or at the solemn feasts, are the same as those which were appointed to be offered with the morning and evening lamb. (Exodus 29:38.) Meal offerings and drink offerings had already been prescribed in connection with the three great feasts. (Leviticus 23:13; Leviticus 23:18; Leviticus 23:37.)
