In the fourth quarter of the seventh chapter of Song of Songs in the Old Testament, Solomon, the wise and rich king of Israel, wrote 1005 poem, among which Song of Songs is a love song. In the fifth song, the groom praised the bride like this: "... your neck is like an ivory tower. Your eyes are near the gate of Bartrabbi in Heshbon, like a pool ... (... your neck is like an ivory tower; Your eyes are like a pool near the sliding door of Heshbon Patna; ……)。
The ivory tower here is only used to describe the bride's beautiful neck.
