Song of Solomon 4:4

4Your neck is like the tower of David, which was built with ramparts: a thousand shields are hanging from it, all the armor of the strong.
4:4The groom describes his bride using the metaphor of a fortress of war. +This image of the tower with a thousand shields is cited in Ineffabilis Deus as a symbolism describing the Virgin Mary, therefore, this is the groom describing the bride. Her strength is from God and is found in God, so she is like an impregnable in her holiness and faith. Also, the neck is what supports the head, and the Church herself supports its head (the Pope leading the Bishops) with the strength and fortitude of a fortress of war.(Conte)
