Concerning Tithes, One Tenth Shall Be Holy To The Lord, Leviticus 26-27.

‘You shall not make idols for yourselves; neither a carved image nor a sacred pillar shall you rear up for yourselves; nor shall you set up an engraved stone in your land, to bow down to it; for I am the Lord your God. You shall keep My Sabbaths and reverence My sanctuary: I am the Lord. ‘If you walk in My statutes and keep My commandments, and perform them, These are the statutes and judgments and laws which the Lord made between Himself and the children of Israel on Mount Sinai by the hand of Moses. If a man wants at all to redeem any of his tithes, he shall add one-fifth to it. And concerning the tithe of the herd or the flock, of whatever passes under the rod, the tenth one shall be holy to the Lord. He shall not inquire whether it is good or bad, nor shall he exchange it; and if he exchanges it at all, then both it and the one exchanged for it shall be holy; it shall not be redeemed.’ ” These are the commandments which the Lord commanded Moses for the children of Israel on Mount Sinai.
