Leviticus 23:21-25

On this very day you shall make a proclamation as well; you are to have a holy convocation. You shall do no laborious work. It is to be a permanent statute in all your dwelling places throughout your generations.

‘When you reap the harvest of your land, moreover, you shall not reap to the very edges of your field nor gather the gleaning of your harvest; you are to leave them for the needy and the stranger. I am the Lord your God.’ ”

Again the Lord spoke to Moses, saying,

“Speak to the sons of Israel, saying, ‘In the seventh month on the first of the month you shall have a rest, a reminder by blowing of trumpets, a holy convocation.

You shall not do any laborious work, but you shall present an offering by fire to the Lord.’ ” The Day of Atonement
