David said to all the assembly, Now bless Yahweh your God. All the assembly blessed Yahweh, the God of their fathers, and bowed down their heads, and worshiped Yahweh, and the king.
"And they bowed down their heads and worshipped Jehovah, and the king"  (1 Chronicles 29:20).  The worship of any man is sinful, even the worship of a great king like David; and this verse should be translated as in the RSV, "All the assembly bowed their heads and worshipped the Lord, and did obeisance to the king."
