“Zadok therefore and Abiathar carried the ark of God again to Jerusalem: and they tarried there.”
King James Version (KJV)
15:27 A seer - A seeing, discerning, or observing man: for so the Hebrew verb raah is often used. And this suits well with David's mind: Thou art a wise man, and therefore fit to manage this great business, which requires prudence and secrecy.
15:30 Barefoot - In testimony of his deep sorrow, and humiliation and shame for his sins.
