'Thanks' in the Bible
The priests stood at their posts [ready for service], and the Levites also, with the musical instruments of the Lord which King David had made to praise the Lord, saying, “For His lovingkindness and mercy endure forever,” whenever David offered praise through their ministry. The priests were opposite the Levites blowing the trumpets and all Israel was standing.
When he had consulted with the people, he appointed those who sang to the Lord and those who praised Him in their holy (priestly) attire, as they went out before the army and said, “Praise and give thanks to the Lord, for His mercy and lovingkindness endure forever.”
Hezekiah spoke encouragingly to all the Levites who showed good understanding in the things of the Lord. So the people ate for the appointed seven days, sacrificing peace offerings and giving thanks to the Lord God of their fathers.
And Hezekiah appointed the divisions of the priests, and the Levites by their divisions, each in accordance with his service, both the priests and Levites, for burnt offerings and for peace offerings, to minister and to give thanks and to praise in the gates of the camp of the Lord.
