New Defender's Study Bible Notes
3:6 Not a novice. See I Timothy 5:22. A bishop must be an “elder”—that is, a man older and more mature in Christian faith and life.
3:6 condemnation of the devil. Pride is thus identified as the worst sin of all, as it was the very sin which caused Lucifer to fall and become Satan, the Devil (Isaiah 14:12-15; Ezekiel 28:14-18). Pride, of course, is essentially identical with the arrogance of rejecting God’s Word.
3:7 snare of the devil. There are five times in the New Testament when believers are warned about a “snare.” In addition to this verse, see also: Luke 21:35; Romans 11:9; I Timothy 6:9; II Timothy 2:26.
