2 Timothy 2:4

4 No soldier in active service entangles himself in the affairs of everyday life, so that he may please the one who enlisted him as a soldier.

2 Timothy 2:14

14 Remind them of these things, and solemnly charge them in the presence of God not to wrangle about words, which is useless and leads to the ruin of the hearers.

2 Timothy 4:16

16 At my first defense no one supported me, but all deserted me; may it not be counted against them.
