For the king of Babylon stood at the parting of the way, at the head of the two ways, to use divination: he made his arrows bright, he consulted with images, he looked in the liver. For the king of Babylon stood at the parting of the way - He was in doubt which way he should first take; whether to humble the Ammonites by taking their metropolis, Riblath, or go at once against Jerusalem. In this case of uncertainty, he made use of divination. And this was of three kinds: 1. By arrows. 2. By images or talismans. 3. By inspecting the entrails of a sacrifice offered on the occasion.
1. He made bright his arrows. This might be after the manner in which the divination is still practiced among the Arabs. These arrows were without head or wing. They took three. On one they wrote, Command me, Lord. On the second, Forbid me, Lord. The third was blank. These were put in a bag, and the querist put in his hand and took one out. If it was Command me, he set about the business immediately; if it was Forbid me, he rested for a whole year; if it was the blank one, he drew again. On all occasions the Arabs consulted futurity by such arrows. See D'Herbelot, under the word Acdah.
2. As to the images, the Hebrew calls them תרפים teraphim. See the note on Genesis 31:19 (note).
3. And as to the liver, I believe it was only inspected to see whether the animal offered in sacrifice were sound and healthy, of which the state of the liver is the most especial indication. When the liver is sound, the animal is healthy; and it would have been a bad omen to any who offered sacrifice, to find that the animal they had offered to their gods was diseased; as, in that case, they would have taken for granted that the sacrifice was not accepted.
