But that it spread no farther - Not the news of the miraculous healing of the lame man, but the doctrine and influence which these men preach and exert. More than a thousand people had already professed faith in Christ in consequence of this miracle, (see Acts 4:4), and if this teaching should be permitted to go on, probably accompanied with similar miracles, they had reason to believe that all Jerusalem (themselves excepted, who had steeled their hearts against all good) should be converted to the religion of him whom they had lately crucified.

Let us straitly threaten them - Απειλῃ απειλησωμεθα, Let us threaten them with threatening, a Hebraism, and a proof that St. Luke has translated the words of the council into Greek, just as they were spoken.

That they speak ...to no man in this name - Nothing so ominous to them as the name of Christ crucified, because they themselves had been his crucifiers. On this account they could not bear to hear salvation preached to mankind through him of whom they had been the betrayers and murderers, and who was soon likely to have no enemies but themselves.

But that it spread no further among the people,.... Meaning not in Jerusalem; for the fame of this miracle was spread among all the inhabitants of that city; but in other parts of the nation:

let us straitly threaten them; or "in threatening threaten them"; that is, severely threaten them with imprisonment, or with the scourging of forty stripes save one, or with death itself.

That they speak henceforth to no man in this name; which through indignation and contempt they do not mention, but mean the name of Jesus: and their sense is, that the apostles, from this time forward, should not teach, or preach the doctrine of the resurrection of the dead, or any other doctrine of the Gospel, in the name of Jesus, to any man, Jew or Gentile; or perform any miracle in his name, or call upon his name, and make use of it, for the healing of any person, or doing any miraculous work. The Ethiopic version is a very odd one, and quite contrary to the sense of the sanhedrim, "that they should not speak any more but in the name of the man Jesus".

It spread (διανεμηθῇ)

Only here in New Testament. Lit., be distributed. In 2 Timothy 2:17, "their word will eat as a canker," is, literally, will have distribution or spreading (νομὴν ἕξει). Bengel, however, goes too far when he represents the members of the council as speaking in the figure of a canker. "They regard the whole as a canker."

But that it spread no further among the people, let us straitly threaten them, that they speak henceforth to no man in this name.

4:17 Yet that it spread no farther - For they look upon it as a mere gangrene. So do all the world upon genuine Christianity. Let us severely threaten them - Great men, ye do nothing. They have a greater than you to flee to.

17. But that it spread no further . let us straitly-strictly.

threaten . that they speak henceforth to no man in this name-Impotent device! Little knew they the fire that was burning in the bones of those heroic disciples.

4:15-22 All the care of the rulers is, that the doctrine of Christ spread not among the people, yet they cannot say it is false or dangerous, or of any ill tendency; and they are ashamed to own the true reason; that it testifies against their hypocrisy, wickedness, and tyranny. Those who know how to put a just value upon Christ's promises, know how to put just contempt upon the world's threatenings. The apostles look with concern on perishing souls, and know they cannot escape eternal ruin but by Jesus Christ, therefore they are faithful in warning, and showing the right way. None will enjoy peace of mind, nor act uprightly, till they have learned to guide their conduct by the fixed standard of truth, and not by the shifting opinions and fancies of men. Especially beware of a vain attempt to serve two masters, God and the world; the end will be, you can serve neither fully.
