Verses for they sang

Is not this David, of whom they sang one to another in dances, saying, Saul slew his thousands, and David his ten thousands?

Moreover Hezekiah the king and the princes commanded the Levites to sing praise unto the LORD with the words of David, and of Asaph the seer. And they sang praises with gladness, and they bowed their heads and worshipped.

And they sang together by course in praising and giving thanks unto the LORD; because he is good, for his mercy endureth for ever toward Israel. And all the people shouted with a great shout, when they praised the LORD, because the foundation of the house of the LORD was laid.

Then believed they his words; they sang his praise.
