One should not bless what Jesus Christ cursed.
Jesus Christ cursed the earthly city of Jerusalem. Matthew 23:37-38.

When you “pray for the peace of Jerusalem,” you are supposed to be praying for the Church of Jesus Christ, not a city in the Middle-East. Almost every Epistle starts with a prayer for peace for the Church; this is not a mistake. Example: “to the churches of Galatia, grace to you and peace from God our Father and our Lord Jesus Christ.” Galatians 1:2.

Earthly Jerusalem is a city of bloodshed.
See Matthew 23:34-36 and Revelation 18:24 below.

The Heavenly Jerusalem is the Church of Jesus Christ. Hebrews 12:22.
Those of us in Jesus Christ have already come to Mount Zion.

Matthew 23:37-38
Jerusalem, Jerusalem who kills the prophets and stones those who are sent to her!
Behold your house is being left to you desolate.

Revelation 18:24
And in here was found the blood of the prophets and of the saints and of all who have been slain on the earth.

Matthew 23:31-35
So you testify against yourselves that you are sons of those who murdered the prophets. Fill up then the measure of the guilt of your fathers. You serpents, you brood of vipers, how will you escape the sentence of hell? Therefore behold, I am sending you propets and wise men and scribes; some of them you will kill and crucify and some of them you will scourge in your synagogues and persecute from city to city, so that the guilt of all the righteous blood shed on earth, from the blood of Zechariah, the son of Berechiah, whom you murdered between the Temple and the altar.
