John Calvin on Acts 13:45

45. They were filled. It is no new matter for the rage of the wicked to be inflamed when the light of the gospel is set somewhat nearer; especially when they see the increase of sound doctrine, they break out with greater violence to resist. And it is to be doubted whether Luke do mean, by the word zeal, that they were moved with a certain wicked indignation, to set themselves against Paul and Barnabas, as ambition is the mother as well of envy as of all contention; or he take zeal for indignation conceived thereupon, because they did lament that the Gentiles were made equal with the people of God. For they counted this a very unmeet thing, that the holy treasure of doctrine, which was the proper inheritance of the children, should he, as it were, at all men’s feet.

Gainsaying and blaspheming. They were so sore set upon resisting, that they brake out at length into blasphemy. And Satan doth for the most part drive the wicked unto such madness, that when they be overcome with reasons and discouraged, they wax harder and harder; and wittingly and willingly they spew out at length blasphemies against God and the truth. Wherefore we must take so much the more heed when as the truth of God is plainly set before us, lest, if we be carried away with a desire to speak against it, we fall straightway into that steep down. “In illud praecipitium ruamus,” we rush instantly over that precipice.

Acts 13:46-52

46. And when Paul and Barnabas had taken liberty, [or boldness,] they said, It was necessary that we should. first preach the word of God to you. And after that ye reject it, and do not judge yourselves worthy of eternal life, behold, we turn unto the Gentiles. 47. For thus hath the Lord commanded us: I have made thee a light of the Gentiles, that thou mayest be the salvation unto the end of the earth. 48. And when the Gentiles heard, they rejoiced, and glorified the word of the Lord; and they believed, as many as were ordained unto eternal life. 49. And the word of the Lord was spread abroad throughout the whole region. 50. And the Jews stirred certain religious and honest women, and the chief men of the city, and they raised persecution against Paul and Barnabas, and expelled them out of their coasts. 51. And they shaked up the dust of their feet against them, and came to Iconium. 52. And the disciples were filled with joy and with the Holy Ghost.
