2 Timothy 1:8; 2 Timothy 2:14; 2 Timothy 4:16

8 Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God;
14 Of these things put them in remembrance , charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers .
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.
