11. "Walk about Zion, and embrace her" (ver. 11). Be it said to them who live ill, in the midst of whom is the people, which hath received the mercy of God. In the midst of you is a people living well, "Walk about Zion." But how? "embrace her." Not with scandals, but with love go round about her: that so those who live well in the midst of you ye may imitate, and by imitation of them, be incorporate with Christ, whose members they are. "Walk about Zion, go round about her: speak in the towers thereof." In the height of her bulwarks, set forth the praises thereof.
