Guard Your Heart Against False Prophets
Even a prophet whose sign comes true is rejected if he says follow other gods; your Father is testing whether you love him with all your heart. The same holds for a beloved brother, wife or friend, and for a whole town: this is the gravest danger to Israel.
13 1If a prophet or dreamer of dreams arises among you and gives you a sign or wonder, 2and the sign or wonder he spoke of comes true, saying, 'Let's follow other gods you have not known, and let's serve them,' 3do not listen to the words of that prophet or dreamer of dreams. Your Father is testing you, to know whether you love your Father with all your heart and all your soul. 4Follow your Father, fear him, keep his commands, obey his voice, serve him, cling to him. 5That prophet or dreamer of dreams must be put to death, because he spoke rebellion against your Father, who brought you out of Egypt and rescued you from the slave house, to drive you off the way your Father commanded you to walk. So purge the evil from among you.
6If your brother, your mother's son, or your son or daughter, or the wife you hold close, or your friend dear as your life, secretly lures you, saying, 'Let's go and serve other gods'—gods you and your ancestors never knew, 7from the gods of the peoples around you, near or far, from earth's one end to the other.' 8Don't consent or listen to him; don't pity, spare, or hide him. 9No—you must put him to death. Your hand strikes first, then all the people's. 10Stone him to death, for he tried to turn you from your Father, who brought you out of Egypt, out of the slave house. 11All Israel will hear and be afraid, and never again do such an evil thing among you.
12If you hear it said of one of your cities your Father gives you to live in, 13worthless men have gone out from among you and led their city's people astray, saying, 'Let's go and serve other gods you haven't known,' 14then search, examine, and ask carefully. If it's true and confirmed that this detestable thing was done among you, 15you must strike down that city's residents with the edge of the sword, destroying it completely—everything in it and its livestock—with the edge of the sword. 16Gather all its plunder into the middle of its square, burn the city and all its plunder in fire as a whole burnt offering to your Father. It stays a ruin forever, never rebuilt. 17Let nothing devoted to destruction cling to your hand, so your Father turns from his burning anger, gives you compassion, has mercy on you, and multiplies you, as he swore to your ancestors, 18if you obey your Father's voice, keeping all his commands I command you today, doing right in your Father's eyes.
