And Moses lifted up his hand, and with his rod he struck the rock twice: and the water came out abundantly, and the congregation drank, and their animals also.
All Commentaries on Numbers 20:11 Go To Numbers 20
Augustine of Hippo
AD 430
We recognize that we are taking a trip in a wasteland. If we recognize ourselves in a wasteland, we are in a wasteland. What does it mean, in a wasteland? In a desert. Why in a desert? Because in this world, one thirsts on a waterless road. But let us thirst that we may be filled. For “blessed are they who hunger and thirst for justice; for they shall have their fill.” And our thirst is filled from a rock in the wasteland. For “the rock was Christ.” And it was struck with a rod that water might flow. But that it might flow, it was struck twice; for there are the two pieces of wood on the cross.
