Sickness, which yields the third type of suffering, is a commoner experience than the two preceding. The picture is lightly sketched, emphasis being laid on the cause of the sickness, which is sin, in accordance with the prevailing view in the Old Testament. The psalmist introduces the persons of whom he is to speak by the strongly condemnatory term "foolish ones," which refers not to intellectual feebleness, but to moral perversity. All sin is folly. Nothing is so insane as to do wrong. An ingenious correction has been suggested, and is accepted by Cheyne in the wake of Dyserinck, Graetz, and others, by which "sick men" is read for "foolish men." But it does not appear to the present writer to be so impossible as Cheyne thinks to "conceive the psalmist introducing a fresh tableau by an ethical term such as fools." The whole verse (17) lays more stress on the sin than on the sickness, and the initial designation of the sufferers as "fools" is quite in harmony with its tone. They are habitual evil-doers, as is expressed by the weighty expression "the way (or course) of their transgression." Not by one or two breaches of moral law, but by inveterate, customary sins, men ruin their physical health. So the psalmist uses a form of the verb in ver. 17_b_ which expresses that the sinner drags down his punishment with his own hands. That is, of course, eminently true in such gross forms of sin as sow to the flesh, and of the flesh reap corruption. But it is no less really true of all transgression, since all brings sickness to the soul. Ver. 18 is apparently quoted from Job xxxiii. 20-22. It paints with impressive simplicity the failing appetite and consequent ebbing strength. The grim portals, of which Death keeps the keys, have all but received the sick men; but, before they pass into their shadow, they cry to Jehovah, and, like the other men in distress, they too are heard, feeble as their sick voice may be. The manner of their deliverance is strikingly portrayed. "He sent His word and healed them." As in Psalm cv. 19, God's word is almost personified. It is the channel of the Divine power. God's uttered will has power on material things. It is the same great thought as is expressed in "He spake and it was done." The psalmist did not know the Christian teaching that the personal Word of God is the agent of all the Divine energy in the realm of nature and of history, and that a far deeper sense than that which he attached to them would one day be found in his words, when the Incarnate Word was manifested, as Himself bearing and bearing away the sicknesses of humanity, and rescuing not only the dying from going down to the grave, but bringing up the dead who had long lain there. God, who is Guide and Emancipator, is also Healer and Life-giver, and He is all these in the Word, which has become flesh, and dwelt and dwells among men.
Another travel-scene follows. The storm at sea is painted as a landsman would do it; but a landsman who had seen, from a safe shore, what he so vividly describes. He is impressed with the strange things that the bold men who venture to sea must meet, away out there beyond the point where sea and sky touch. With sure poetic instinct, he spends no time on trivial details, but dashes on his canvas the salient features of the tempest,--the sudden springing up of the gale; the swift response of the waves rolling high, with new force in their mass and a new voice in their breaking; the pitching craft, now on the crest, now in the trough; the terror of the helpless crew; the loss of steering power; the heavy rolling of the unmanageable, clumsy ship; and the desperation of the sailors, whose wisdom or skill was "swallowed up," or came to nothing.
