Deuteronomy 26:13

Then thou shalt say before the LORD thy God, I have brought away the hallowed things out of mine house, and also have given them unto the Levite, and unto the stranger, to the fatherless, and to the widow, according to all thy commandments which thou hast commanded me: I have not transgressed thy commandments, neither have I forgotten them:

Thou shalt say before the Lord thy God. This was a solemn and conscientious declaration that nothing which should be devoted to the divine service had been secretly reserved for personal use.
