Deuteronomy 13:1
If there arise among you a prophet, or a dreamer of dreams, and giveth thee a sign or a wonder, (Deuteronomy 13:1)
If there arise.
Preferably, “when there arises.”
A prophet.
Literally, a “spokesman” or “speaker.” The word thus translated is from a root meaning “to utter a low voice,” “to announce,” “to pass on information.”
A dreamer.
 The Hebrew words here used refer to ordinary dreams (Isa. 29:8; Ps. 126:1), to inspired dreams, as those of Jacob (Gen. 28:12), of Joseph (Gen. 37:5-10), of Nebuchadnezzar (Dan. 2:1-3), and of false prophets, as here (Jer. 23:25).
Sign.
From ’oth, meaning a “sign,” “token,” given, or a “miracle” performed, to attest an inspired message and to encourage those who witness it to cooperate faithfully with the divine will.
Wonder.
 Literally, a “symbol,” “sign,” “portent,” or “symbolic act,” sent in token of some future event. This refers to a special display of power by a true prophet (Ex. 7:3; 11:9; Ps. 105:5), or by a false prophet, as here.
