Acheinu (Hebrew: אַחֵינוּ, Our brothers) is a Jewish prayer calling for the release of captives.
It is akin to similar calls to liberate captives on other Jewish occasions, such as the Passover seder.
[2] In the 1980s, songwriter Abie Rotenberg composed a niggun based on the Acheinu prayer text,[3] which he included on his 1990 album Lev V’Nefesh.
[4] During the Israel-Hamas war and the enduring hostage crisis, "Acheinu" became a common anthem for Jewish communities[5][3][6] alongside the more upbeat "Am Yisrael Chai", with "Acheinu" sung more frequently at funerals, shivas, and prayer times.
Jewish a cappella group The Maccabeats sung "Acheinu" at the March for Israel, and political commentator Ben Shapiro sang the song during his syndicated radio show.
