Leviticus 23:22-24

Amplified Bible, Classic Edition

²² And when you reap the harvest of your land, you shall not wholly reap the corners of your field, neither shall you gather the gleanings of your harvest; you shall leave them for the poor and the stranger. I am the Lord your God.

²³ And the Lord said to Moses,

²⁴ Say to the Israelites, On the first day of the seventh month [almost October], you shall observe a day of solemn [sabbatical] rest, a memorial day announced by blowing of trumpets, a holy [called] assembly.
