The song leaves standing a single unfinished act of thanksgiving. In Greek Byzantine chant the voice keeps naming who is owed praise — the Lord who is good, the God of gods, the Lord of lords, the One who alone works great wonders — and every naming is answered by the same hinge: hoti is ton eona to eleos aftou, for his mercy endures forever, sealed with Alliluia.

Nothing here advances like a story; the refrain becomes the room you remain inside. A solo male cantor carries the lines over a continuous drone, pulse steady and bodily, weight suspended rather than driven, the surface warm and held almost without rupture until it simply fades. The music practices the forever it claims: praise as sustained standing, not climax. Heard this way, Psalm 135 is less a text recited than a living Orthodox litany still doing its work — mercy that does not run out, kept audible by a tradition that never needed the words to finish.
