Leviticus 23:15-17

¹⁵Therefore ye shall number from the tother day of the sabbath, in which ye offered handfuls of the first fruits, seven full weeks,

¹⁶till to the tother day of filling of the seventh week, that is, fifty days; and so ye shall offer a new sacrifice to the Lord,

¹⁷of all your dwelling places, two loaves of the first fruits, of two tenth parts of tried flour, dighted with sour-dough, which loaves ye shall bake into the first fruits to the Lord.
