Genesis 15:17. And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.
The “burning lamp” is supposed to have been an emblem of the Divine presence, as fire is represented to be in other parts of the Scriptures. Roberts says that in India the burning lamp or fire is still used in confirmation of a covenant. If one’s promise is doubted he will point to the flame of the lamp, saying, “That is the witness.” The marriages of the East Indian gods and demigods are described as being performed in the presence of the God of fire; and it is to this day a general practice at the celebration of a marriage to have fire as a witness of the transaction. “Fire is the witness of their covenant, and, if they break it, fire will be their destruction.” Orient.
