Tithes

22 aYou shall tithe all the yield of your seed that comes from the field year by year.

Deuteronomy 26:12-15

12When you have finished paying all bthe tithe of your produce in the third year, which is cthe year of tithing, giving it to the Levite, the sojourner, the fatherless, and the widow, so that they may eat within your towns and be filled, 13then you shall say before the Lord your God, ‘I have removed the sacred portion out of my house, and moreover, I have given it to the Levite, the sojourner, the fatherless, and the widow, according to all your commandment that you have commanded me. I have not transgressed any of your commandments, dnor have I forgotten them. 14 eI have not eaten of the tithe while I was mourning, or removed any of it while I was unclean, or offered any of it fto the dead. I have obeyed the voice of the Lord my God. I have done according to all that you have commanded me. 15 gLook down from your holy habitation, from heaven, and bless your people Israel and the ground that you have given us, as you swore to our fathers, a land flowing with milk and honey.’
