But be not thou far from me, O LORD: O my strength, haste thee to help me.
Ver. 19. But be not thou far from me, O Lord] Here he resumeth and reinforceth his former prayer, after a most pathetic description of his so doleful condition. Faith wadeth out of trouble (as the moon doth out of a cloud) by hearty and affectionate prayer.
O my strength] God is so to a believer, then especially when he feeleth himself weak as water.
Haste thee to help me] Who am now in an exigent, and am therefore bold, without limitation, to request thee to haste away to me.
