It has been good for me that I was afflicted. He here confirms the sentiment which we have previously considered -- that it was profitable to him to be subdued by God's chastisements, that he might more and more be brought back and softened to obedience. By these words he confesses that he was not exempt from the perverse obstinacy with which all mankind are infected; for, had it been otherwise with him, the profit of which he speaks, when he says that his docility was owing to his being brought low, would have been merely pretended; even as none of us willingly submits his neck to God, until He soften our natural hardness by the strokes of a hammer. It is good for us to taste continually the fruit which comes to us from God's corrections, that they may become sweet to us; and that, in this way, we, who are so rebellious and wayward, may suffer ourselves to be brought into subjection. The last verse also requires no exposition, as it contains a sentiment of very frequent occurrence in this psalm, and, in itself, sufficiently plain, -- That he preferred God's law to all the riches of the world, the immoderate desire of which so deplorably infatuates the great bulk of mankind. He does not compare the law of God with the riches he himself possessed; but he affirms, that it was more precious in his estimation than a vast inheritance.

It is good for me that I have been afflicted - See the notes at Psalm 119:67. Whatever may have been the form of the affliction, it was good for me. The design was benevolent; the result has been my own benefit. This will be the experience sooner or later resulting from all the afflictions of the righteous.
That I might learn thy statutes - That I might be brought more fully to understand what they require; and that I might be led to conform to them. It is implied here
(a) that this is the tendency of affliction; and
(b) that this is an advantage - a good.
Anything that will lead a man to obey God is a blessing and a favor. Whatever leads a sinner to secure the salvation of his soul is a gain to him. No matter what it may cost; no matter what he may be required to give up; no matter to what persecutions and troubles it may expose him; no matter what he may suffer, or how long he may suffer; no matter though poverty, contempt, toil - even the rack or the stake - may be the consequence of his religion - yet it is again to him; and he will be thankful for it in the end - for nothing that can be endured in this life can be compared with the sufferings of the world of despair; nothing on earth can be "compared with the glory which shall be revealed in us in heaven." See the notes at Romans 8:18.

It is good for me that I have been afflicted - See on Psalm 119:67 (note).

[It is] (d) good for me that I have been afflicted; that I might learn thy statutes.
(d) He confesses that before he was chastened he was rebellious as man by nature is.

It is good for me that I have been afflicted,.... The good and profit of which he had observed before; See Gill on Psalm 119:67. The following end being also answered thereby,
that I might learn thy statutes; to understand them, and to keep them. Afflictions are sometimes as a school to the people of God, in which they learn much both of their duty and of their privileges; and when they are teaching and instructive, they are for good; see Psalm 94:12.

So also affliction of any kind acts as a wholesome discipline in leading the pious more highly to value the truth and promises of God.
