“Those who have wisely surrounded Zion and embraced it spiritually climb up onto its towers. There they tell of it to those not able to ascend its turrets.… Always the insidious foe has his eye on it, to see if he can approach and capture it. For Satan has his armies, and with them he lays siege to souls. He has siege engines that he moves up close to the walls so as to take its towers by force. But you, says the psalm, must preach from the towers.… Preach, proclaim, without intermission, without end.
“Ver. 12. Walk about Zion; often beat her bounds, even as Israel marched around Jericho. With leisurely and careful inspection survey her. And go round about her. Encircle her again and again with loving perambulations. We cannot too frequently or too deeply consider the origin, privileges, history, security, and glory of the church. Some subjects deserve but a passing thought; this is worthy of the most patient consideration. Tell the towers thereof. See if any of them have crumbled, or have been demolished. Is the church of God what she was in doctrine, in strength and in beauty?
“The call to survey Zion, or the Church, as a fortified city, is designed to suggest "how well our God secures His fold." This security is perpetual, and its pledge is His guidance through this life.
“Some think this refers to the ceremony of the triumph; let those who are employed in that solemnity walk round the walls (as they did, Neh. xii. 31 ), singing and praising God.

Rare words are the text's own signal of a deliberate thread — the fewer the occurrences, the more the places it appears belong together.
And you, O watchtower of the flock, O stronghold of the Daughter of Zion— the former dominion will be restored to you; sovereignty will come to the Daughter of Jerusalem.”
Then I brought the leaders of Judah up on the wall, and I appointed two great thanksgiving choirs. One was to proceed along the top of the wall to the right, toward the Dung Gate.
Look upon Zion, the city of our appointed feasts. Your eyes will see Jerusalem, a peaceful pasture, a tent that does not wander; its tent pegs will not be pulled up, nor will any of its cords be broken.
