Clarke's Bible Commentary - 2 Timothy 4:15
Verse 15. Of whom be thou ware also] It seems that this rabbin traveled about from place to place for the purpose of opposing the Gospel, the Jews putting him forward, as it is said, Acts xix. 33. He hath greatly withstood our words.] Has been a constant opposer of the Christian doctrines.
John Gill's Bible Commentary
Ver. 15. Of whom be thou ware also , etc.] For he was now at Ephesus; and since he was such a malicious, ill natured, and troublesome person, as well as a blasphemer, an heretic, and had been delivered up to Satan, it was very advisable to shun his company, and have no conversation with him, and be upon the guard against him, that he might have no opportunity of doing hurt to him, or to the church at Ephesus: for he hath greatly withstood our words : or doctrines; the truths of the Gospel preached by Paul and Timothy, which he opposed himself to, and resisted with all his might, and endeavoured to confute and overthrow; and wherein he was deficient in argument, he made up with railing and blasphemy; and this was the true reason of the apostle's imprecations on him, and why he would have Timothy beware of him, and avoid him, and not the personal injury he had done him.
Matthew Henry Commentary
Verses 14-18 - There is as much danger from false brethren, as from open enemies. It is dangerous having to do with those who would be enemies to such a ma as Paul. The Christians at Rome were forward to meet him, Ac 28, but when there seemed to be a danger of suffering with him, then all forsook him. God might justly be angry with them, but he prays God to forgive them. The apostle was delivered out of the mouth of the lion that is, of Nero, or some of his judges. If the Lord stands by us, he will strengthen us in difficulties and dangers, and his presence wil more than supply every one's absence.

15. Greatly withstood (lian antesth). Comp. chapter iii. 8, and Gal. ii. 11. This may refer to the occurrences at Ephesus (Acts xix. 33), or to Alexander's attitude during Paul's trial. The former is more probable. Lian greatly, not in Paul, except in the compound uJperlian, 2 Corinthians xi. 5; xii. 11. Only here in Pastorals. Mostly in Synoptic Gospels.
