But now it is come upon thee, and thou faintest; it toucheth thee, and thou art troubled.

But now the scourge is come upon thee, and thou faintest: it hath touched thee, and thou art troubled.

But now it is come upon thee, and thou grievest; it toucheth thee, and thou art troubled.

But now, it cometh in unto thee, And thou art weary; It striketh unto thee, and thou art troubled.

But now it has come on you and it is a weariness to you; you are touched by it and your mind is troubled.

But now it is come upon thee, and thou art weary; It toucheth thee, and thou art affrighted.

But now the scourge has overcome you, and you falter. It has touched you, and you are disturbed.

But now it is come upon thee - That is, calamity; or, the same trial which others have had, and in which thou hast so successfully exhorted and comforted them. A similar sentiment to that which is here expressed, is found in Terence:
Facile omnes, cum valemus, recta consilia aegrotis damus.
And. ii. i. 9.
It toucheth thee - That is, affliction has come to yourself. It is no longer a thing about which you can coolly sit down and reason, and on which you can deliver formal exhortations.
And thou art troubled - Instead of evincing the calm submission which you have exhorted others to do, your mind is now disturbed and restless. You vent your complaints against the day of your birth, and you charge God with injustice. A sentiment resembling this, occurs in Terence, as quoted by Codurcus:
Nonne id flagitium est, te aliis consilium dare,
Foris sapere, tibi non posse te auxiliarier?
Something similar to this not unfrequently occurs. It is an easy thing to give counsel to others, and to exhort them to be submissive in trial. It is easy to utter general maxims, and to suggest passages of Scripture on the subject of affliction, and even to impart consolation to others; but when trial comes to ourselves, we often fail to realize the power of those truths to console us. Ministers of the gospel are called officially to impart such consolations, and are enabled to do it. But when the trial comes on them, and when they ought by every solemn consideration to be able to show the power of those truths in their own case, it sometimes happens that they evince the same impatience and want of submission which they had rebuked in others; and that whatever truth and power there may have been in their instructions, they themselves little felt their force. It is often necessary that he who is appointed to comfort the afflicted, should be afflicted himself. Then he can "weep with those who weep;" and hence, it is that ministers of the gospel are called quite as much as any other class of people to pass through deep waters. Hence, too, the Lord Jesus became so pre-eminent in suffering, that he might be touched with the feelings of our infirmity, and be qualified to sympathize with us when we are tried; Hebrews 2:14, Hebrews 2:17-18; Hebrews 4:15-16. It is exceedingly important that when they whose office it is to comfort others are afflicted, they should exhibit an example of patience and submission. Then is the time to try their religion; and then they have an opportunity to convince others that the doctrines which they preach are adapted to the condition of weak and suffering man.

But now it is come upon thee - Now it is thy turn to suffer, and give an example of the efficacy of thy own principles; but instead of this, behold, thou faintest. Either, therefore, thou didst pretend to what thou hadst not; or thou art not making a proper use of the principles which thou didst recommend to others.

But now it is come upon thee, and thou faintest,.... The affliction and evil that he feared, Job 3:25; or rather the same trials and afflictions were come upon him as had been on those whom he had instructed and reproved, and whose hands and hearts he had strengthened and comforted; and yet now thou thyself "faintest", or "art weary" (z), or art bore down and sinkest under the burden, and bearest it very impatiently (a), quite contrary to the advice given to others; and therefore it was concluded he could not be a virtuous, honest, and upright man at heart, only in show and appearance. Bolducius renders the words, "God cometh unto thee", or "thy God cometh"; very wrongly, though the sense may be the same; God cometh and visits thee by laying his afflicting hand upon thee:
it toucheth thee, and thou art troubled; suggesting that it was but a touch, a slight one, a light affliction; thereby lessening Job's calamity and distress, or making little and light of it, and aggravating his impatience under it, that for such a trial as this he should be so excessively troubled, his passions should be so violently moved, and he be thrown into so much disorder and confusion, and be impatient beyond measure; no bounds being set to his grief, and the expressions of it; yea, even to be in the utmost consternation and amazement, as the word (b) signifies.

thou art troubled--rather, "unhinged," hast lost thy self-command (1-Thessalonians 3:3).
