23 But foolish and unlearned questions avoid, knowing that they do gender strifes.
23 Don't have anything to do with foolish and stupid arguments, because you know they produce quarrels.
23 Have nothing to do with foolish, ignorant controversies; you know that they breed quarrels.
23 Refuse to get involved in inane discussions; they always end up in fights.
23 But avoid foolish and ignorant disputes, knowing that they generate strife.
23 Again I say, don't get involved in foolish, ignorant arguments that only start fights.
10 A man that is an heretick after the first and second admonition reject;
10 Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them.
10 As for a person who stirs up division, after warning him once and then twice, have nothing more to do with him,
10 Warn a quarrelsome person once or twice, but then be done with him.
10 Reject a divisive man after the first and second admonition,
10 If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them.
(Read Titus 3:8-11)
When the grace of God towards mankind has been declared, the necessity of good works is pressed. Those who believe in God, must make it their care to maintain good works, to seek opportunities for doing them, being influenced by love and gratitude. Trifling, foolish questions must be avoided, and subtle distinctions and vain inquiries; nor should people be eager after novelties, but love sound doctrine which tends most to edifying. Though we may now think some sins light and little, if the Lord awaken the conscience, we shall feel even the smallest sin heavy upon our souls.
Matthew Henry's Commentary on 2 Timothy 2:23
Commentary on 2 Timothy 2:22-26
(Read 2 Timothy 2:22-26)
The more we follow that which is good, the faster and the further we shall flee from that which is evil. The keeping up the communion of saints, will take us from fellowship with unfruitful works of darkness. See how often the apostle cautions against disputes in religion; which surely shows that religion consists more in believing and practising what God requires, than in subtle disputes. Those are unapt to teach, who are apt to strive, and are fierce and froward. Teaching, not persecution, is the Scripture method of dealing with those in error. The same God who gives the discovery of the truth, by his grace brings us to acknowledge it, otherwise our hearts would continue to rebel against it. There is no "peradventure," in respect of God's pardoning those who do repent; but we cannot tell that he will give repentance to those who oppose his will. Sinners are taken in a snare, and in the worst snare, because it is the devil's; they are slaves to him. And if any long for deliverance, let them remember they never can escape, except by repentance, which is the gift of God; and we must ask it of him by earnest, persevering prayer.
