'Sing' in the Bible

Then he consulted with the people and appointed some to sing for the Lord and some to praise the splendor of His holiness. When they went out in front of the armed forces, they kept singing:Give thanks to the Lord,for His faithful love endures forever.

Then King Hezekiah and the officials told the Levites to sing praise to the Lord in the words of David and of Asaph the seer. So they sang praises with rejoicing and bowed down and worshiped.
