From the Koren Shalem Siddur:
May He who blessed our ancestors, Abraham, Isaac and Jacob, Joseph, Moses and Aaron, David and Solomon, bless, protect and guard the members of Israel’s Defense Forces missing in action or held captive, and other captives among our brethren, the whole house of Israel, who are in distress or captivity, as we, the members of this holy congregation, pray on their behalf. May the Holy One, blessed be he, have compassion on them and bring them out from darkness and the shadow of death; may He break their bonds, deliver them from their distress, and bring them swiftly back to their families’ embrace. Give thanks to the LORD for His loving-kindness and for the wonders He does for the children of men; and may there be fulfilled in them the verse: “Those redeemed by the LORD will return; they will enter Zion with singing, and everlasting joy will crown their heads. Gladness and joy will overtake them, and sorrow and sighing will flee away.” And let us say: Amen.
