New Defender's Study Bible Notes
22:8 shed much blood. The house of God must speak primarily of peace between man and God, so it was inappropriate that it be built by a man of war, even though David had merely been completing the conquest of the promised land—the conquest begun long before at God’s command by Joshua.
22:10 my son. This reference confirms God has a Son! This prophecy of the everlasting kingdom is fulfilled only in Christ. See Hebrews 1:5.
