PBV 'How long wilt thou forget me, O Lord, for ever?' A single question instead of the double one of AV. 'Forget for ever' means 'continue to forget.' The seemingly self-contradictory form of the question reflects the conflict of the writer's feelings, 'Hope despairs and yet despair hopes' (Luther). Note the four repetitions of 'how long' in Psalms 13:1; Psalms 13:2.
