Genesis

And he built there an altar, and called the place El–beth–el: because there God appeared unto him, when he fled from the face of his brother.

And blessed be the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all.

Honour the Lord with thy substance, and with the firstfruits of all thine increase:

Thou shalt truly tithe all the increase of thy seed, that the field bringeth forth year by year.

And thou shalt eat before the Lord thy God, in the place which he shall choose to place his name there, the tithe of thy corn, of thy wine, and of thine oil, and the firstlings of thy herds and of thy flocks; that thou mayest learn to fear the Lord thy God always.
