Leviticus 23:11-13

¹¹And he shall uplift the omera before the Lord to be accepted for you: after the day of the festivity (yoma taba) shall the priest uplift it.

¹²And you shall perform on the day of your elevation of the omera (the sacrifice of) an unblemished lamb of the year, as a burnt offering before the Lord.

¹³And the mincha thereof shall be two-tenths of flour mingled with oil, an oblation to be accepted before the Lord; and its libation, wine, the fourth of a hin.
