Deuteronomy 14:23

And thou shalt eat before the Lord, thy God, in the place which He shall choose to place His name there, the central Sanctuary which He intended to select in Canaan, the tithe of thy corn, that is, of grain in general, of thy wine, and of thine oil, and the firstlings of thy herds and of thy flocks, chap, 12:5-7, that thou mayest learn to fear the Lord, thy God, always. The fear of the Lord does not only include the feeling of utter dependence upon Him, but includes also the idea of piety, and Israel, with the proper reverence; was to rejoice in the fellowship of the covenant God.
