“Moses sent to spy on Yazer, and they captured its environs and dispossessed the Emorites who were there” (Numbers 21:32). “Israel dwelled in the cities of the Emorites” (Numbers 21:25) – Yazer remained; “Moses sent to spy on Yazer.” Those spies were diligent. They said: We are certain of Moses’ prayer, but he already sent spies in the past and they brought about a mishap. We will not do so, but rather we will put our faith in the Holy One blessed be He and wage war. They did so and killed “the Emorites who were there.”
