7. Wherefore he goes on to say, “I have laboured in my groaning.” And as if this availed but little, he adds, “I will wash each night my couch” (ver. 6). That is here called a couch, where the sick and weak soul rests, that is, in bodily gratification and in every worldly pleasure. Which pleasure, whoso endeavours to withdraw himself from it, washes with tears. For he sees that he already condemns carnal lusts; and yet his weakness is held by the pleasure, and willingly lies down therein, from whence none but the soul that is made whole can rise. As for what he says, “each night,” he would perhaps have it taken thus: that he who, ready in spirit, perceives some light of truth, and yet, through weakness of the flesh, rests sometime in the pleasure of this world, is compelled to suffer as it were days and nights in an alternation of feeling: as when he says, “With the mind I serve the law of God,” he feels as it were day; again when he says, “but with the flesh the law of sin,” he declines into night: until all night passeth away, and that one day comes, of which it is said, “In the morning I will stand by Thee, and will see.” For then he will stand, but now he lies down, when he is on his couch; which he will wash each night, that with so great abundance of tears he may obtain the most assured remedy from the mercy of God. “I will drench my bed with tears.” It is a repetition. For when he says, “with tears,” he shows with what meaning he said above, “I will wash.” For we take “bed” here to be the same as “couch” above. Although, “I will drench,” is something more than, “I will wash:” since anything may be washed superficially, but drenching penetrates to the more inward parts; which here signifies weeping to the very bottom of the heart. Now the variety of tenses which he uses; the past, when he said, “I have laboured in my groaning;” and the future, when he said, “I will wash each night my couch;” the future again, “I will drench my bed with tears;” this shows what every man ought to say to himself, when he labours in groaning to no purpose. As if he should say, It hath not profited when I have done this, therefore I will do the other.
