It is added, [1] There is no one who doeth kindness By this we are to understand, that they had put off every feeling of humanity. For as the best bond of mutual concord among us is the knowledge of God, (as he is the common Father of all, he wonderfully unites us, and without him there is nothing but disunion,) so inhumanity commonly follows where there is ignorance of God, as every one, when he despises others, loves and seeks his own good.

Footnotes

1 - This verse is literally the Septuagint, and as to meaning, a correct version of the Hebrew. "All have gone out of the way -- pantes exeklinan" "is in Hebrew hkl sr, "the whole (or every one) has turned aside," or revolted, or apostatized. Then, "they have become unprofitable" or useless, is n'lchv, "they are become putrid," or Corrupted, like putrified fruit or meat, therefore useless, not fit for what they were designed -- to serve God and to promote their own and the good of others. Idolatry was evidently this putrescence. -- Ed.

They have all gone out of the way - They have "declined" from the true path of piety and virtue.
They are together - They have at the same time; or they have equally become unprofitable. They are as one; they are joined, or united in this declension. The expression denotes union, or similarity.
Become unprofitable - This word in Hebrew means to become "putrid" and "offensive," like fruit that is spoiled. In Arabic, it is applied to "milk" that becomes sour. Applied to moral subjects, it means to become corrupt and useless. They are of no value in regard to works of righteousness.
There is none - This is taken literally from the Hebrew.

They are all gone out of the way - παντες εξεκλιναν, they have all diverged from the right way, they have either abandoned or corrupted the worship of God: the Jews, in forsaking the law and the prophets, and the Gentiles, in acting contrary to the law which God had written on their hearts. And the departure of both from the truth proves the evil propensity of human nature in general.
They are together become unprofitable - ηχρειωθησαν. They are useless, good for nothing; or, as the Hebrew has it, נאלחו neelachu, they are putrid: he views the whole mass of mankind as slain and thrown together, to putrefy in heaps. This is what is termed the corruption of human nature; they are infected and infectious. What need of the mercy of God to save from such a state of degeneracy!
There is none that doeth good - In Romans 3:10 it is said, There is none righteous; here, There is none that doeth good: the first may refer to the want of a righteous principle; the second, to the necessary consequence of the absence of such a principle. If there be no righteousness within, there will be no acts of goodness without.

They are all gone out of the way,.... In Psalm 14:3; it is said, "they are all gone aside"; as persons in debt: man had a considerable stock of righteousness, holiness, knowledge, &c. but he has run through all, has contracted large and numerous debts, has been obliged to hide himself, has been used as a bankrupt, and turned out of house and home: Christ indeed has undertook to pay, and he has paid all the debts of his people; and has put them into a better state than ever Adam was in: in Psalm 53:3, it is rendered, "everyone of them is gone back"; that is, from God; from his commands, and from their former state and condition: here the phrase is rendered by the apostle, "they are all gone out of the way": that is, out of the way of God and his precepts, out of the way of holiness and righteousness, of light and life; into their own ways, the ways of sin, Satan, and the world of darkness, and of death: so Aben Ezra explains it, "out of the right way"; Kimchi and Ben Melech paraphrase it, "out of the good way: and so"
they are together become unprofitable; the word in Psalm 14:3 and Psalm 53:3; is translated, "they are become filthy"; which R. Aben Ezra interprets by "they are corrupt"; and R. Solomon Jarchi by , "they are turned to corruption"; the metaphor is taken from stinking flesh, which is tainted and corrupted, and so good for nothing, hence here rendered "unprofitable"; for so men being corrupted by sin, are of no use, service, and advantage to God, to men, or to themselves; but, on the contrary, nauseous to God, and to all that are good, and hurtful to themselves and others: for
there is none that does good, no, not one; and therefore must be unprofitable. There is none that can do good in a spiritual manner, without the grace of God, strength from Christ, and the assistance of the Spirit; and there is not even a spiritual man, that can do good perfectly, and without sin.

They have all turned aside - From the good way. They are become unprofitable - Helpless impotent, unable to profit either themselves or others.
