Psalms 147:12

Praise the Lord, O Jerusalem; praise your God, O Zion. Just now we heard the holy presbyter preaching that, because of its transgression of the law, the Jewish people has been forsaken; and how is it that now it is said, Praise the Lord, O Jerusalem; praise your God, O Zion? Praise the Lord, O Jerusalem. Jerusalem, "vision of peace." Praise your God, O Zion. Zion is interpreted "watchtower." You see, then, what he says: Praise the Lord, O Jerusalem. Wherever there is a vision of peace, wherever there is contemplation of God, there let there be praise of God. Praise the Lord, then, O Church, when you have begun to believe in him and to have peace, and have begun to see peace: this is Jerusalem, "vision of peace." You who were formerly of the idols have been made the servant of God: praise, then, your God. But when you have begun already to have knowledge, and to be a watchtower — this is Zion — praise the Lord: that is, you praise Jerusalem, you praise Zion, you soul of the Church, you Church. Let not the heretics praise, let not the synagogue praise, but you praise.

We have found a great protector, brothers. You know that people rely on their protectors. To someone threatening, a client of a greater man responds: "With the life of my lord safe, you do nothing to me." How much more strongly and surely can we say: "With our head safe, you do nothing to us?" For our protector is our head. Whoever relies on any human protector is a client of that person; we are members of our protector. May he hold us to him, and no one will tear us away from him. For whatever hardships we have suffered in this world, all that passes is nothing. Good things will come which will not pass away; we reach them through hardships. But once we have reached them, no one can tear us away from there. The gates of Jerusalem are closed, they even have bars, so that it may be said to that city: "Praise the Lord, Jerusalem; praise your God, Zion. For he has strengthened the bars of your gates, he has blessed your children within you. He has set your borders with peace." With the gates closed, bars in place, no friend leaves, no enemy enters. There we have true and certain security, if we have not abandoned the truth here.

"Praise in unison, O Jerusalem, thy God." Abiding yet in captivity, they behold those flocks, or rather, the one flock of all its citizens, gathered from all sides into that city; they see the joy of the mass, now after threshings and winnowings placed in the garner, fearing nothing, suffering no toil nor trouble; and, as yet abiding here, in the midst of the threshing they send forward their joy of hope, and pant for it, joining as it were their hearts to the Angels of God, and to that people which shall abide with them in joy for ever. For what wilt thou then do, O Jerusalem? Surely toil and groaning will pass away. What wilt thou do? wilt thou plough, or sow, or plant vines, or make voyages, or trade? What wilt thou do? Will it still be thy duty to be engaged in the works thou now doest, good though they are, and spring from mercy? Consider thy numbers, consider on all sides thy company: see whether any hungers, for thee to give bread to; see whether any thirsts, for thee to give a cup of cold water to; see whether any is a stranger, for thee to take in; see whether any is sick, for thee to visit; see whether any is at strife, for thee to reconcile him; see whether any is dying, for thee to bury him. What then wilt thou do? "Praise in unison, O Jerusalem, thy God." Behold, this is thy business. As is wont to be said in inscriptions, "Use it and be happy."
