Charles Ellicott Commentary Leviticus 23:13

"And the meal-offering thereof shall be two tenth parts [of an ephah] of fine flour mingled with oil, an offering made by fire unto Jehovah for a sweet savor; and the drink-offering thereof shall be of wine, the fourth part of a hin." — Leviticus 23:13 (ASV)

Two tenth deals of fine flour. —Ordinarily only one-tenth deal of fine flour was required for a meat-offering (Exodus 29:40; Numbers 15:4; Numbers 28:9; Numbers 28:13, etc.), to exhibit the plentiful harvest. With the exception of the handful of flour and oil, and of all the frankincense, this meat-offering was the perquisite of the priests. (See Leviticus 2:2-3.)
