Levítico 23

The Feast of Weeks

15 From the day after the Sabbath, the day you brought the sheaf of the wave offering, you are to count off seven full weeks.

22 When you reap the harvest of your land, do not reap all the way to the edges of your field or gather the gleanings of your harvest. Leave them for the poor and the foreign resident. I am the LORD your God.’"
