1 Corinthians, Chapter 9, verses 13-18
1 He showeth his liberty, and that the minister ought to live by the gospel, 15 yet that himself hath of his own accord abstained, 18 to be either chargeable unto themMatthew, Chapter 16, verses 1-6
1 The Pharisees require a sign, 6 Jesus warneth his disciples of the leaven of the Pharisees and Sadducees16
16:1 A sign from heaven - Such they imagined Satan could not counterfeit. Mar 8:11; Mat 12:38.
16:2 Luk 12:54.
16:3 The signs of the times - The signs which evidently show, that this is the time of the Messiah.
16:4 A wicked and adulterous generation - Ye would seek no farther sign, did not your wickedness, your love of the world, which is spiritual adultery, blind your understanding.
16:5 Mar 8:14.
16:6 Beware of the leaven of the Pharisees - That is, of their false doctrine: this is elegantly so called; for it spreads in the soul, or the Church, as leaven does in meal. Luk 12:1.

9:14 Mat 10:10
9:15 It were better for me to die than - To give occasion to them that seek occasion against me, Co2 11:12.
9:17 Willingly - He seems to mean, without receiving anything. St. Paul here speaks in a manner peculiar to himself. Another might have preached willingly, and yet have received a maintenance from the Corinthians. But if he had received anything from them, he would have termed it preaching unwillingly. And so, in the next verse, another might have used that power without abusing it. But his own using it at all, he would have termed abusing it. A dispensation is intrusted to me - Therefore I dare not refrain.
9:18 What then is my reward - That circumstance in my conduct for which I expect a peculiar reward from my great Master? That I abuse not - Make not an unseasonable use of my power which I have in preaching the gospel.
