שְׁאִילוּ בִּשְׁלָמָא דִירוּשְׁלֶם יֵתְבוּן בְּשַׁלְוָתָא רְחִימָיִךְ.
1. Pray for the peace | שַׁאֲלוּ שְׁלוֹם יְרוּשָׁלָ͏ִם – More literally: "ask for…" but see Metzudat David and Hoil Moshe that the connotation is "ask of Hashem". The language of "שאלו" was likely chosen so as to alliterate with the words "שְׁלוֹם", "יִשְׁלָיוּ" and "יְרוּשָׁלָ͏ִם", all containing some combination of the sounds "ש", "ל" and "מ". The word "שְׁלוֹם" itself repeats three times in these closing verses. The identity of the speaker of these words is unclear. The palmist might be talking to his fellow pilgrims or alternatively, it is the residents of Jerusalem who speak, telling the departing pilgrims to always keep the city in their prayers.
2. May those who love you | יִשְׁלָיוּ אֹהֲבָיִךְ – With these words the psalmist once again directly addresses the city. Alternatively, this (and the following verses) is the content of the request one is supposed to make when "praying for the peace of Jerusalem".
