In the previous chapter, Moses commanded Israel to completely destroy all the idols in Canaan, Deuteronomy 12:2-3, and they were commanded not to add or take away anything from God’s commands, Deuteronomy 12:32 / Deuteronomy 4:5. In this chapter, Moses moves on to speak about those false prophets who represented those false gods. This is the first of three cases of apostasy that are mentioned in this chapter.
This first case would be a false prophet who would give what would appear to be a sign or make a prediction that would appear to be a fulfilled prophecy, Deuteronomy 13:1-2 / Matthew 24:24 / 2 Thessalonians 2:9 / Revelation 13:13 / Revelation 13:14. We must remember that dreams can be from God, Numbers 12:6 / Genesis 37:5-11, or they can be false prophesies, Jeremiah 23:25-26. If a prophet made a prediction and that prediction come to pass, Deuteronomy 18:22, the people may be curious and would often listen to what they said.
Moses said if these false prophets encourage Israel to follow other gods, and worship them, they shouldn’t listen to these false prophets, Deuteronomy 13:2-3. When they said something which contradicted God’s law, as this was a sign that the dreams of the prophet had originated in their own minds and not from God, 1 Kings 22:6-8 / 1 Kings 22:20-23 / Isaiah 8:19-20 / Jeremiah 6:13 / Jeremiah 28:1-17.
Notice that this is one way Israel would be tested by God, Deuteronomy 13:3 / Deuteronomy 8:2-4 / Deuteronomy 8:15-16. It appears that the Lord allowed hardships and false teaching to happen, to see if Israel truly loved Him with all their heart and soul, or not, Deuteronomy 13:4 / Deuteronomy 8:12 / Deuteronomy 8:20-21 / Deuteronomy 11:1 / Deuteronomy 11:13 / Deuteronomy 11:22. This also means that Israel can’t claim to love God if they don’t keep His commands, John 14:15.
Clarke, in his commentary, says the following.
‘God permits such impostors to arise to try the faith of his followers, and to put their religious experience to the test; for he who experimentally knows God cannot be drawn away after idols. He who has no experimental knowledge of God, may believe anything. Experience of the truths contained in the word of God can alone preserve any man from Deism, or a false religion.’
God knows how dangerous these false prophets were and so He commands if they are proven to be false, they must be put to death, Deuteronomy 13:5 / Acts 20:29-30. In fact, He commands Israel to ‘purge the evil from among you’, Deuteronomy 13:5. We see this happening with Elijah who slaughtered the false prophets of Baal, 1 Kings 18:40.
Barnes, in his commentary, says the following.
‘The context and parallel passages, Deuteronomy 17:7 / Leviticus 20:2, indicate that there was to be a regular judicial procedure, and that the manner of the execution was to be by stoning. In this the community was to take its part in order to show its horror at the crime, and to clear itself of complicity therein.’
Here Moses speaks about a very difficult situation, where a false prophet turns out to be part of your family. This second temptation refers to one close in the family or a dear friend, someone who would encourage Israel to follow and worship other gods, Deuteronomy 13:6-7 / Matthew 10:37 / 1 Timothy 2:14.
Moses tells Israel, rather than tolerating, accepting, or even following these family members’ false teaching, the people of God weren’t to yield to them, listen to them, have no pity on them, not to spare them or shield them Deuteronomy 13:8.
They were to kill them, they must personally kill them with their own hands, and everyone should lay their hands on the heads of the false teacher to kill him, Deuteronomy 13:9-10. The reason for them being stoned to death was also to create fear in the hearts of Israel and to prevent these evil things from happening again, Deuteronomy 13:11.
Over and over again Moses has reminded Israel, that they shouldn’t follow or fall for false religion, Deuteronomy 6:14 / Deuteronomy 7:1-5 / Deuteronomy 12:2-3 / Deuteronomy 20:15-18. This same principle is also taught throughout the New Testament, Matthew 7:21-23 / Matthew 10:34-39 / Luke 14:25-35.
Here Moses deals with the third temptation that Israel may face, that is, a group of false prophets who may lead whole towns astray, they are described as troublemakers, those who encourage Israel to follow and worship other gods, Deuteronomy 13:12-13. Note that some translations call them ‘children of Belial’, which means, worthlessness, Deuteronomy 15:9 / Nahum 1:11.
If a group of false prophets were to seduce an entire city to follow their wicked ways, then God’s people who heard of the event, were to inquire more about the story, search the information, and ask diligently about the matter to many sources, Deuteronomy 13:14.
If the story is found to be true, that is, an entire group of people from a town has been drawn away by these teachers, then God’s people were to take further action, they were completely destroying the inhabitants of the town along with their cattle, Deuteronomy 13:15 / 2 Thessalonians 2:3-4.
Clarke, in his commentary, says the following.
‘If one city were permitted to practise idolatry, the evil would soon spread, therefore the contagion must be destroyed in its birth.’
After the town of false teachers and worshippers is destroyed, the Israelites were to gather all the spoils of that town into the middle of the street and burn it with fire, Deuteronomy 13:16 / Deuteronomy 7:25-26. God then commands that such a place should never be rebuilt, Deuteronomy 13:16 / Joshua 6 / Joshua 7 / Judges 20:38 / Judges 20:48.
God’s people were to have disgust and hatred over the condemned things the false teacher taught, Deuteronomy 13:17 / Deuteronomy 7:26 / Leviticus 27:26-29 / Romans 12:9. If Israel do as God commands, the He would turn from His fierce anger and show them mercy, and will have compassion on them, He will also increase their numbers, as He promised on oath to your ancestors, Deuteronomy 13:17-18.
It would be just to say that God’s people must be in fear of forsaking the word of God or distorting it in any way that would lead to immoral behaviour on the part of God’s people.
