Deuteronomy 13:1-3

13:1 If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, 13:2 And the sign or the wonder come to pass, whereof he spake unto thee, saying, Let us go after other gods, which thou hast not known, and let us serve them; 13:3 Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.

Jeremiah 29:8

29:8 For thus saith the LORD of hosts, the God of Israel; Let not your prophets and your diviners, that [be] in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed.
