"A Dreamer Of Dreams"

Context: Moses, an old man after leading the Israelites through the wilderness for about forty years, has reached the Jordan River and has been told by God that he can never cross into Canaan. He gathers the Israelites together and explains God's purpose for them by restating the commandments and laws. He implores the people to ignore a false prophet who would lead them into idolatry and away from God. He explains that God tests their loyalty by allowing such a prophet to perform miracles and to dream dreams of true revelation, and that the Israelites are to ignore him and cleave to the Lord. (Cf. William Morris: "Dreamer of dreams, born out of my due time . . .")

If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder,
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;
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.
