When he had said these things. This is added, in order to inform us, first, how great was the rage of the enemies of Christ, and how tyrannical their government was; and, secondly, what sort of discipline existed among those priests. They sit like judges, but they are as cruel as ferocious beasts. A council is assembled, in which the utmost gravity ought to have prevailed; and yet a single officer is so daring and presumptuous, that, in the midst of the judicial proceedings, and in the presence of the judges, he strikes the person accused, who was not found to be in any respect guilty. We need not wonder, therefore, that the doctrine of Christ is condemned by so barbarous an assembly, from which not only all justice, but likewise all humanity and modesty, are banished.

One of the officers - One of the inferior officers, or those who attended on the court.
With the palm, of his hand - This may mean: "Gave him a blow either with the open hand or with a rod" - the Greek does not determine which. In whatever way it was done, it was a violation of all law and justice. Jesus had showed no disrespect for the office of the high priest, and if he had, this was not the proper way to punish it. The Syriac reads thus: "Smote the cheek of Jesus." The Vulgate and Arabic: "Gave him a blow."

One of the officers - struck Jesus - This was an outrage to all justice: for a prisoner, before he is condemned, is ever considered to be under the especial protection of justice; nor has any one a right to touch him, but according to the direction of the law. But it has been observed before that, if justice had been done to Christ, he could neither have suffered nor died.

And when he had thus spoken,.... What was so right and reasonable, in so becoming a manner, without heat or passion:
one of the officers which stood by; it may be one of those who had been sent to him and had been a hearer of him, whom Jesus might look wistfully at, or point unto, when he said the above words, at which he might be provoked: and therefore
stroke Jesus with the palm of his hand; or gave him a rap with a rod, or smote him with a staff, as some think, is the sense of the phrase; though the Syriac, agreeably to our version, reads it, he smote him, , "upon his cheek"; gave him, what we commonly call, a slap on the face; and which is always esteemed a very great affront, and was a piece of rudeness and insolence to the last degree in this man:
saying, answerest thou the high priest so? This he said, as well as gave the blow, either out of flattery to the high priest, or to clear himself from being a favourer of Christ; which, by what had been said, he might think would be suspected: some have thought this was Malchus, whose ear Christ had healed; if so, he was guilty of great ingratitude.

struck Jesus with the palm . . . Answerest Thou the high priest so--(See Isaiah 50:6; and compare Acts 23:2). (Also see on Mark 14:54.)

Answerest thou the high priest so? - With so little reverence?
