Deuteronomy 26:10-11

Thou shalt set it The basket of first-fruits; before the Lord That is, before the sanctuary, where God was more especially present. This shows that the person offering this oblation was to hold the basket in his hand while he made the foregoing acknowledgment. And worship before the Lord Bowing his body, as the original word imports, toward the holy place, which external sign of inward worship, in all truly pious men, was accompanied with gratitude of heart to God for his benefits, and with prayer for their continuance. And thou shalt rejoice Thou shalt hereby be enabled to take comfort in all thy enjoyments, when thou hast sanctified them by giving God his portion. It is the will of God that we should be cheerful, not only in our attendance upon his holy ordinances, but in our enjoyment of the gifts of his providence. Whatever good thing God gives us, we should make the most comfortable use of it we can, still tracing the streams to the fountain of all consolation.
