'Thank Offerings' in the Bible

Then Hezekiah said, “Now that you have consecrated yourselves to the Lord, come near and bring sacrifices and thank offerings to the house of the Lord.” And the assembly brought sacrifices and thank offerings, and all those who were willing brought burnt offerings.

He set up the altar of the Lord and sacrificed peace offerings and thank offerings on it; and he ordered Judah to serve the Lord God of Israel.

Your vows are binding upon me, O God;I will render thank offerings to You.
