Charles Ellicott Commentary Psalms 122:6-7

"Pray for the peace of Jerusalem: They shall prosper that love thee. Peace be within thy walls, And prosperity within thy palaces." — Psalms 122:6-7 (ASV)

It is impossible in English to reproduce the effect of the original in these references to the usual greetings of the East, since at the same time they contain alliterations and a play on the name of Jerusalem. There is first the challenge to the body of pilgrims to give the customary salutation, and then it is taken up in a threefold wish, varied each time. Then follows the reason of this unanimous and hearty prayer: Ask for the peace of the city of peace; prosperity be to thy lovers, peace within thy walls, prosperity in thy palaces.
