(17) Let us straitly threaten them.--The Greek gives literally, let us threaten them with threats. The phrase gives the Hebrew idiom for expressing intensity by reduplication, as in "blessing I will bless thee" (Genesis 22:17), "dying thou shalt die" (Genesis 2:17, marg.), and, as far as it goes, indicates that St. Luke translated from a report of the speech which Caiaphas had delivered in Aramaic. It is a perfectly possible alternative that the High Priest, speaking in Greek, reproduced, as the LXX, often does, the old Hebrew formula.

Verse 17. - Threaten for straitly threaten, A.V. and T.R. The subject of that it spread seems to be "a notable miracle." They could not deny that it had taken place, but they could prevent the knowledge of it spreading, by forbidding the apostles to speak of the Name of Jesus in which it had been wrought.

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.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".
