A prophet (nabhi, נבָיִא); one who speaks from God, an interpreter to men of what God reveals or suggests to him (of. for the meaning of the word, Exodus 7:1 with Exodus 4:16; also Jeremiah 15:19). Dreamer of dreams. Not by visions or immediate suggestion only, but also by means of dreams, did God communicate with men (cf. Numbers 12:6). The case supposed here, then, is that of one pretending to have had revelations from God through those media by which God was pleased to convey his will to men (cf. Hem; 'Iliad,' h 62—
" ἀλλ ἄγε δή τινα μάντιν ἐρείομεν ….
ἢ καὶ ὀνειροπόλον καὶ γάρ τ̓ ὄναρ ἔκ διός ἐστιν)"
Sign or a wonder. A sign was some event foretold by the prophet, and the occurrence of which was a token that something else which he announced would happen or should be done. A wonder was a miracle, the performance of which gave proof of a Divine commission (cf. Deuteronomy 4:24). These signs, it is assumed, should come to pass; nevertheless, the people were not to listen to the man who gave them to go after other gods. The mere fact that he sought to persuade them to forsake the worship of Jehovah was sufficient to prove him an impostor; for how could one who sought to seduce the people from God be sent by God? The sign which was given to authenticate such a message could only be one of those "lying signs and wonders after the working of Satan," by which his emissaries try to deceive and mislead; and was permitted by God only that their fidelity to him might be tested and proved. They had already received God's message; they had his word; and no teaching which contravened that, however apparently authenticated, could be from him, or was to he accepted by them (cf. Jeremiah 29:8; Galatians 1:8, Galatians 1:9; 1 John 3:1, etc.). Come what might, they were to walk after Jehovah their God, and keep his commandments, and obey his voice, and serve him; and cleave unto him. The false prophet, as a public enemy and a suborner of treason against the King of Israel, was to be put to death; and so the evil would be put away from among them.
