'Thanksgiving' in the Bible

After this, Hezekiah announced, "Now that you've consecrated yourselves to the LORD, come near and bring your sacrifices and thanksgiving offerings to the LORD's Temple." So the assembly brought sacrifices and thanksgiving offerings, and everyone who was willing to do so brought burnt offerings.

Hezekiah appointed the priestly divisions and the divisions of the descendants of Levi, each according to their service duties, including both priests and descendants of Levi who offered morning and evening burnt offerings, peace offerings, general ministry, thanksgiving, and praise in the gateways to the LORD's campgrounds.

And he built up the altar of Jehovah, and offered thereon sacrifices of peace-offerings and of thanksgiving, and commanded Judah to serve Jehovah, the God of Israel.
