At this time the king of Moab was Balak, who was formerly a vassal of Sihon, and in that capacity was known as Zur. After Sihon's death he was chosen king, though he was not worthy of a rank so high. Favored by fortune, he received royal dignity, a position that his father had never filled. Balak was a fitting name for this king, for he set about destroying the people of Israel, wherefore he was also called the son of Zippor, because he flew as swiftly as a bird to curse Israel.
Balak was a great magician, who employed for his sorcery the following instrument. He constructed a bird with its feet, trunk, and head of gold, its mouth of silver, and its wings of bronze, and for a tongue he supplied it with the tongue of the bird Yadu'a. This bird was now placed by a window where the sun shone by day and the moon by night, and there it remained for seven days, throughout which burnt offerings were offered before it, and ceremonies performed.
At the end of this week, the bird's tongue would begin to move, and if pricked by a golden needle, would divulge great secrets. It was this bird that had imparted to Balak all his occult lore. One day, however, a flame that suddenly leaped up burned the wings of this bird, which greatly alarmed Balak, for he thought that Israel's proximity had destroyed his instrument of sorcery.
