But thou shalt presently put him to death. Let thy hand be first upon him, and afterwards the hands of all the people.

but thou shalt in any case kill him: thy hand shall be the first against him to put him to death, and afterwards the hands of all the people;

'But thou dost surely kill him; thy hand is on him, in the first place, to put him to death, and the hand of all the people last;

But put him to death without question; let your hand be the first stretched out against him to put him to death, and then the hands of all the people.

Instead, you shall put him to death promptly. Let your hand be upon him first, and after that, let the hands of all the people be sent forth.

Sed occidendo occides eum: manus tua erit in eum prima ad ipsum interficiendum, deinde manus universi populi.

But thou shalt surely kill him. He would not that every one should privately execute vengeance without a public trial; but he referred to the ordinary custom, that the witnesses should throw the first stone at condemned criminals, as we shall see elsewhere. For it was an admirable provision, that God would have those who had denounced the crime, to be the executors of its punishment, in order that they should be more cautious and moderate in giving their testimony. The reason, which is added at the end, "because he hath sought to thrust thee away from the Lord thy God, who brought thee out," etc., again exaggerates the crime on the score of its ingratitude; which was detestable in proportion to the inestimable blessing of their deliverance. It was an act of gross wickedness to rebel against God after they had known Him; but it was still more gross to undervalue their Deliverer. Finally, the advantage and fruit of this severity is subjoined; for, whilst punishment was inflicted on one man's crime, all others were inspired with terror; and thus the death of one is a wholesome discipline for all, in the way of example.

But thou shalt surely kill him; (g) thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.
(g) As the witness is charged.

But thou shalt surely kill him,.... Not privately and secretly, when and where he entices, nor the enticed himself by his own authority, but after being examined, judged, and condemned by the civil magistrate; and none might judge a false prophet but the sanhedrim at Jerusalem, the sanhedrim of seventy one (m); see Luke 13:33, but the difficulty is how such an one could be convicted, since the affair was transacted secretly, Deuteronomy 13:6 and there were none present to be witnesses, none but the enticer and the enticed; so that either the enticer must be brought to a confession of his guilt, or the testimony of the enticed alone must be taken. The Jewish doctors say (n), that they laid in wait for the enticer, which they never did for any other person, and the method they took was this; the enticed brought two persons, and put them behind a hedge, so that they might see the enticer, and hear his words, and he not see them; and he said to the enticer, say what thou hast said to me privately; which said, the enticed answered to him, how shall we leave our God which is in heaven, and go and serve wood and stone? if he returned (from his evil) hereby, or was silent, he was free; but if he said unto him, so we are obliged, and thus it is comely for us; they that stood afar off, behind the hedge (or in a dark room), brought him to the sanhedrim, and stoned him, that is, after examination, trial, judgment, and condemnation:
thine hand shall be first upon him, to put him to death; he was to throw the first stone at him, partly to show his indignation against the sin he had enticed him to, and that it had not at all affected him so as to incline him unto it; and partly to show that he had bore a true testimony, of which a suspicion might have been created in the minds of some, had he been backward to the execution of him:
and afterwards the hand of all the people; who then could proceed with more certainty and satisfaction: this shows that the person enticed had not a right to kill the enticer, without a judicial process, and the order of the civil magistrate.

thou shalt surely kill him--not hastily, or in a private manner, but after trial and conviction; and his relative, as informer, was to cast the first stone (see on Deuteronomy 17:2; Acts 7:58). It is manifest that what was done in secret could not be legally proved by a single informer; and hence Jewish writers say that spies were set in some private part of the house, to hear the conversation and watch the conduct of a person suspected of idolatrous tendencies.

To such persuasion Israel was not to yield, nor were they to spare the tempters. The accumulation of synonyms (pity, spare, conceal) serves to make the passage more emphatic. כּסּה, to cover, i.e., to keep secret, conceal. They were to put him to death without pity, viz., to stone him (cf. Leviticus 20:2). That the execution even in this case was to be carried out by the regular authorities, is evident from the words, "thy hand shall be first against him to put him to death, and the hand of all the people afterwards," which presuppose the judicial procedure prescribed in Deuteronomy 17:7, that the witnesses were to cast the first stones at the person condemned.

Thou shalt kill him - Not privately, which pretence would have opened the door to innumerable murders, but by procuring his death by the sentence of the magistrate. Thou shalt cast the first stone at him, as the witness was to do.
