Bible Verses About Prophecy: How tested

If a prophet or a dreamer of dreams arises in your midst you, and he gives you a sign or a wonder,

and the sign or the wonder comes to pass, of which he spoke to you, saying, “Let us go after other gods” (which you have not known) “and let us serve them”;

you shall not listen to the words of that prophet, or to that dreamer of dreams; for the LORD your God is testing you, to know whether you love the LORD your God with all your heart and with all your soul.

When a prophet speaks in the LORD’s name, if the thing doesn’t follow, nor happen, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously. You shall not be afraid of him.
