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 (Isaiah 29:8; Psalm 126:1), to inspired dreams, as those of Jacob (Genesis 28:12), of Joseph (Genesis 37:5-10), of Nebuchadnezzar (Daniel 2:1-3), and of false prophets, as here (Jeremiah 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 (Exodus 7:3; 11:9; Psalm 105:5), or by a false prophet, as here.
