2 Timothy 4:15 KJV

Of whom be thou ware also; for he hath greatly withstood our words.
2 Timothy 4:15, King James Version

In context

14 Alexander the coppersmith did me much evil: the Lord reward him according to his works:

15 Of whom be thou ware also; for he hath greatly withstood our words.

16 At my first answer no man stood with me, but all men forsook me: I pray God that it may not be laid to their charge.
