Deuteronomy 16:1-2

Douay-Rheims 1899 American Edition

16 Observe the month of new corn, which is the first of the spring, that thou mayst celebrate the phase to the Lord thy God: because in this month the Lord thy God brought thee out of Egypt by night.

² And thou shalt sacrifice the phase to the Lord thy God, of sheep, and of oxen, in the place which the Lord thy God shall choose, that his name may dwell there.
