king stood up upon his feet, and
said, Hear me, my brethren, and my
people: As for me, I had in mine
heart to build an house of rest for the ark of the covenant of the Lord, and for the footstool of our God, and had
made ready for the building:

8. 3 But God said unto me, Thou shalt not build an house for my name, because thou hast been a man of war, and hast shed blood.
