15 And you shall count to you from the next day after the sabbath, from the day that you brought the sheaf of the wave offering; seven sabbaths shall be complete.

22 And when you reap the harvest of your land, you shall not completely reap the corner of your field. When you reap the gleaning of your harvest, you shall not gather. You shall leave them to the poor and to the stranger. I [am] the LORD your God.
