This plural noun denotes processions or formal marches. Nehemiah 12:31 describes two 'thanksgiving processions' at the dedication of Jerusalem's rebuilt wall. These processions moved in opposite directions atop the wall, with choirs, musicians, and leaders publicly celebrating God's protection. The word emphasizes organized, ceremonial movement for religious purposes—worship made visible and communal. Such processions embodied Israel's identity as a people gathered around Yahweh.
