Therefore David blessed Yahweh before all the assembly; and David said, You are blessed, Yahweh, the God of Israel our father, forever and ever.
"David blessed Jehovah"  (1 Chronicles 29:10).  We normally think of God's blessing men, not the other way around; but we learn from  1 Chronicles 29:20, below, that when David commanded the people to "Bless Jehovah," they did so by worshipping God and offering sacrifices, all of this being exactly what David did here.  Thus we conclude that those who truly worship God indeed do "bless God."
