 This narrative states that on account of their thirst, the Israelites grumbled against Moses () so Moses, in fear for his life, appeals to Yahweh (); the narrative continues with Yahweh telling Moses to walk ahead of the others, and strike the rock at Horeb with his rod, and when Moses does this, it causes the rock to expel water.The episode recounted by the Book of Numbers features the Israelites quarreling with Moses "and Aaron" about the lack of water "and food crops"; the text states that Moses and Aaron responded by consulting Yahweh at the Tabernacle door, while prostrating themselves, and that Yahweh told them to take the rod, and speak to a particular rock while the people are gathered together in view of it.The narrative continues with Moses following the instructions to take Aaron's staff and to gather the Israelites, but instead of speaking to the rock, which Yahweh had stated would result in water flowing from it, Moses speaks to the "crowd" and strikes the rock, doing so twice, resulting in a strong flow of water.
