Bible Verses About False Prophets: Mode of trying and detecting

`When there ariseth in your midst a prophet, or a dreamer of a dream, and he hath given unto thee a sign or wonder,

and the sign and the wonder hath come which he hath spoken of unto thee, saying, Let us go after other gods (which thou hast not known), and serve them,

`And when thou sayest in thy heart, How do we know the word which Jehovah hath not spoken? --

that which the prophet speaketh in the name of Jehovah, and the thing is not, and cometh not--it is the word which Jehovah hath not spoken; in presumption hath the prophet spoken it; --thou art not afraid of him.

Beloved, every spirit believe not, but prove the spirits, if of God they are, because many false prophets have gone forth to the world;

in this know ye the Spirit of God; every spirit that doth confess Jesus Christ in the flesh having come, of God it is,

and every spirit that doth not confess Jesus Christ in the flesh having come, of God it is not; and this is that of the antichrist, which ye heard that it doth come, and now in the world it is already.
