'Thanksgiving' in the Bible

If he present it for a thanksgiving, then he shall present with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and fine flour saturated with oil, cakes mingled with oil.

Besides the cakes, he shall present his offering of leavened bread with the sacrifice of his peace-offering of thanksgiving.

And the flesh of the sacrifice of his peace-offering of thanksgiving shall be eaten the same day that it is presented; he shall not let any of it remain until the morning.

And when ye sacrifice a sacrifice of thanksgiving to Jehovah, ye shall sacrifice it for your acceptance.
