Thank offering

The thank offering (Hebrew: תֹּודָה, pronounced Todah) or sacrifice of thanksgiving (Hebrew zevakh hatodah זֶבַח הַתֹּודָה ) was an optional offering under the Law of Moses. This is also termed the "thanksgiving offering."

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

The Hebrew noun todah "thanksgiving" is derived from the Hiphil of the verb yadah (יָדָה) "to praise."
