'Lock' in the Bible

I rose up to open to my beloved; And my hands dropped with myrrh, And my fingers with liquid myrrh, Upon the handles of the lock.

And he stretched forth the form of a hand, and took me by a lock of my head; and the Spirit lifted me up between the earth and the heavens, and brought me in the visions of God to Jerusalem, to the entry of the inner gate that looketh toward the north, where was the seat of the image of jealousy, which provoketh to jealousy.
