μακάριοι οὓς ἐξελέξω καὶ προσελάβου → blessed are those that you have chosen and taken
English (Strong)

a primitive root (perhaps ident. with זָמַר through the idea of striking with the fingers); properly, to touch the strings or parts of a musical instrument, i.e. play upon it; to make music, accompanied by the voice; hence to celebrate in song and music: give praise, sing forth praises, psalms.
