15 And when you have counted for yourselves from the day after the Sabbath, the day that you bring the sheaf of the wave offering, seven Sabbaths shall be completed.

22 When you reap the harvest of your land, you shall not completely reap to the corners of your field when you reap, nor shall you gather any gleaning from your harvest. You shall leave them for the poor and for the sojourner: I am Jehovah your God.
