Charles Ellicott Commentary 1 Chronicles 28:3

"But God said unto me, Thou shalt not build a house for my name, because thou art a man of war, and hast shed blood." — 1 Chronicles 28:3 (ASV)

But God said to me. —The emphasis lies on the word God, which is in direct contrast with the “I—in my heart it was,” of 1 Chronicles 28:2. (Compare 1 Chronicles 22:8, of which this verse is a summary.)
