Verse 3. - When any shall yet prophesy; i.e. if any man shall pretend to have predictive powers conferred on him by God. There is here no intimation that true prophecy should cease, as Keil and Kohler suppose; the man is punished, not because he prophesies, but because "he speaketh lies." His father and his mother. The passage is grounded on the enactments in Deuteronomy 13:6-10 and Deuteronomy 18:20, which commanded the death of a false prophet or of one who enticed others to Idolatry. Here the holy zeal of the parents should put the law in force. This was quite a different state of things from that which obtained in former times. The earlier prophets continually complain of the favour shown to these deceivers (comp. Isaiah 9:15; Jeremiah 5:31; Micah 2:11); and we never read of the legal punishment being inflicted after due investigation, the test being the nonfulfilment of the prediction (Deuteronomy 18:22). In the new theocracy, so great is the recoil from such pretenders, that their nearest relations shall at once punish them with death without any previous legal process. Shall thrust him through. Stab, pierce him, put him to death, as in ch. 12:10. The gospel deals more tenderly with heretics (Luke 9:55). "Defendenda religio non est occidendo," says Laetant. ('Div. Inst.,' 5:20), "sed moriendo; religio cogi non potest " (Wordsworth, in loc.).

13:1-6 In the time mentioned at the close of the foregoing chapter, a fountain would be opened to the rulers and people of the Jews, in which to wash away their sins. Even the atoning blood of Christ, united with his sanctifying grace. It has hitherto been closed to the unbelieving nation of Israel; but when the Spirit of grace shall humble and soften their hearts, he will open it to them also. This fountain opened is the pierced side of Christ. We are all as an unclean thing. Behold a fountain opened for us to wash in, and streams flowing to us from that fountain. The blood of Christ, and God's pardoning mercy in that blood, made known in the new covenant, are a fountain always flowing, that never can be emptied. It is opened for all believers, who as the spiritual seed of Christ, are of the house of David, and, as living members of the church, are inhabitants of Jerusalem. Christ, by the power of his grace, takes away the dominion of sin, even of beloved sins. Those who are washed in the fountain opened, as they are justified, so they are sanctified. Souls are brought off from the world and the flesh, those two great idols, that they may cleave to God only. The thorough reformation which will take place on the conversion of Israel to Christ, is here foretold. False prophets shall be convinced of their sin and folly, and return to their proper employments. When convinced that we are gone out of the way of duty, we must show the truth of our repentance by returning to it again. It is well to acknowledge those to be friends, who by severe discipline are instrumental in bringing us to a sight of error; for faithful are the wounds of a friend, Pr 27:6. And it is always well for us to recollect the wounds of our Saviour. Often has he been wounded by professed friends, nay, even by his real disciples, when they act contrary to his word.And it shall come to pass, that when any shall yet prophesy,.... Or attempt to prophesy, or propagate their idolatrous religion and principles after this time, when they shall be abundantly detected and exposed:

then his father and his mother that begat him; of whom he is born, and who, as his parents, must be supposed to have the most tender regard unto him, even to these the imposture will be so flagrant, that they will not encourage him, but, on the contrary,

shall say unto him, Thou shall not live; but die, according to the law against the false prophet in Deuteronomy 18:20,

for thou speakest lies in the name of the Lord; which is the very character of the followers of the man of sin, who speak lies in hypocrisy, pretending that they are of God, and carrying a show of truth; religion, and holiness, 1 Timothy 4:1,

and his father and his mother that begat him shall thrust him through when he prophesieth; so great will be their love to God, and to his truth, that, notwithstanding the nearness of blood, their hands will be upon him first, and either beat him, or put him to death; a son, according to the law, not being to be spared in such a case, Deuteronomy 13:6.
