The Moabites now perceiving that Israel conquered their enemies by supernatural means said, "Their leader had been bred in Midian, let us therefore inquire of the Midianites about his characteristics." When the elders of Midian were consulted, they replied, "His strength abides in his mouth." "Then," said the Moabites, "we shall oppose to him a man whose strength lies in his mouth as well," and the determined to call upon Balaam's support. The union of Moab and Midian establishes the truth of the proverb: "Weasel and Cat had a feast of rejoicing over the flesh of the unfortunate Dog." For there had always been irreconcilable enmity between Moab and Midian, but they united to bring ruin upon Israel, just as Weasel and Cat had united to put an end to their common enemy Dog.
