Kōthel (כֹּתֶל) means wall — specifically a house wall or partition. It appears in the Song of Solomon, where it is cherished in Jewish tradition as the word behind 'Western Wall' (Kotel).
Song of Solomon 2:9: 'My beloved is like a gazelle... Look! There he stands behind our wall, gazing through the windows, peering through the lattice.' The beloved is near — separated only by a wall — looking through every opening to see the one he loves. This is a picture of God's nearness even when we feel a barrier. He is not distant; He is right behind the wall, seeking us. The Hebrew word kōthel lives on today in the Western Wall (Ha-Kotel) in Jerusalem — the closest point to where God's presence dwelt.
