(18) His will.--Literally, the will--i.e., "the supreme will."

Approvest the things that are more excellent.--Probably rightly given in the Authorised version, though the marginal rendering also is possible, "triest the things that differ"--i.e., "art able to discriminate between good and evil."

Being instructed.--With reference to the constant reading of the Law in the synagogue.

Verse 18. - And knowest his will, and approvest the things that are more excellent (δοκιμάζεις τὰ διαφέροντα, a phrase capable also of the meaning, "provest the things which differ," i.e. distinguishest between right and wrong; for δοκιμάζειν may mean either "to prove," or "to approve" after trial, and τὰ διαφέροντα either "things which differ," or "things which surpass." Exactly the same expression occurs in Philippians 1:10, with the same uncertainty of meaning. The difference is unimportant, both interpretations coming to the same thing), being instructed (κατηχούμενος, which implies regular training, whether catechetically in youth, or through rabbinical and synagogic teaching) out of the Law. So far the Jew's own claims on the ground of his own position have been touched on; what follows expresses his attitude with regard to others. We may observe throughout a vein of irony.

2:17-24 The apostle directs his discourse to the Jews, and shows of what sins they were guilty, notwithstanding their profession and vain pretensions. A believing, humble, thankful glorying in God, is the root and sum of all religion. But proud, vain-glorious boasting in God, and in the outward profession of his name, is the root and sum of all hypocrisy. Spiritual pride is the most dangerous of all kinds of pride. A great evil of the sins professors is, the dishonour done to God and religion, by their not living according to their profession. Many despise their more ignorant neighbours who rest in a dead form of godliness; yet themselves trust in a form of knowledge, equally void of life and power, while some glory in the gospel, whose unholy lives dishonour God, and cause his name to be blasphemed.And knowest his will,.... Not the secret will or purpose of God; nor his revealed will in the Gospel, for of this they were ignorant; but his declared will in the law, showing what is to be done, and what is not to be done: to know which in express terms was a privilege, that other people had not; but then the bare knowledge of this will be of no avail: for persons may know their Lord's will, as the Jews did, and not do it, and so be worthy to be beaten with many stripes:

and approvest the things that are more excellent: or "triest the things that differ"; from one another, and from the will and law of God; or as the Syriac, "discernest" "things that are convenient"; agreeable, which are fit and ought to be done: and having tried and discerned them, they approved of them in their judgment as the things more excellent; but then they did not put these excellent things in practice which they approved of; and the knowledge and approbation they had of these things, arose from their

being instructed out of the law, and not the Gospel; for the excellent things of the Gospel, they had no discerning, knowledge and approbation of; see Philippians 1:10.
