The enthusiasm manifested by the prophet in his mode of address, or in his endurance of insult and ill-treatment, made him sometimes appear in the eyes of the public as though he were struck with madness, so that scoffers used ‏נביא‎ and ‏משגע‎ “mad,” as synonyms (Jer. xxix. 26), and ‏מתנבא‎ is both one who acts as a prophet and one who imitates the appearance of a prophet (1 Sam. xviii. 10). The false prophets are divided by Jeremiah into three classes: there were those who were guilty of a direct plagiarism, preaching the Divine messages of the true prophets and describing them as their own inspiration. There were others who plagiarised and reproduced true prophecies in a form and style of their own, and others again who altogether invented dreams and visions. The principal test for distinguishing between the true and the false prophets was the purity of moral and religious conduct. In matters wholly indifferent as regards morality and religion the prophet was believed after having established his trustworthiness in some way or other, and his advice was acted upon. The prophet himself could easily detect the fraud of a false prophet; for what he was commanded by God to do, another prophet could not, speaking in the name of the same God, order not to be done. The prophet, therefore, who deceitfully induced “the man of God” to return to Beth-el by the very way which the word of God had forbidden him to go again (1 Kings xiii. 18), could not have been a true prophet, although he was subsequently entrusted with a Divine message for “the man of God.” Bileam was likewise for a certain purpose made the bearer of God’s words, although he was by no means a good man. In either case the sinful intention of the false prophet was stigmatised as contrary to the Will of the Most High, and both had, as it were, to own the wickedness of their intention or the wrong of their actions. The subject-matter of the prophecy is called “the vision,” “the word of God,” or “the burden of the word of God.” In the days of Jeremiah the term “burden of the Lord” seems to have been used contemptuously of the prophetic utterances in the sense of “trouble” and “strife” (comp. Deut. i. 12), and the prophet was ironically asked by the people, “What is the burden of the Lord?” Jeremiah exhorts them to say, “What hath the Lord answered thee?” or “What hath the Lord spoken?” “But the burden of the Lord shall ye remember no more; for the burden shall be the man’s to whom His word is brought” (Jer. xxiii. 36).
