Psalm 139 is the 139th psalm of the Book of Psalms, beginning in English in the King James Version: "O Lord, thou hast searched me, and known me". In Latin, it is known as "Domine probasti me et cognovisti me". The psalm is a hymn psalm. Attributed to David, it is known for its affirmation of God's omnipresence. Alexander Kirkpatrick states that "the consciousness of the intimate personal relation between God and man which is characteristic of the whole Psalter reaches its climax here".
