Leviticus 23:13-16

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.

¹⁴Neither bread, nor parched corn, nor green ears shall you eat until this day when you bring the oblation of your God; an everlasting statute unto your generations in all your dwellings.

¹⁵And count to you, after the festival day, from the day that you brought the omera of the elevation, seven weeks, complete shall they be.

¹⁶Until the (day) after the seventh week number fifty days, and (then) offer a new mincha before the Lord.
