But thou, O God, shalt bring them down into the pit of destruction: bloody and deceitful men shall not live out half their days; but I will trust in thee.
Bloody and deceitful men shall not live out half their days - literally, 'men of bloods and of deceit shall not halve their days' (Psalms 102:23; Proverbs 10:27).
But I will trust in thee - and therefore shall be delivered (Psalms 52:8).
