Moses strikes the “flint rock” in the wilderness, and water gushes out, turning the wilderness into a garden (Deuteronomy 8:15).
Israel is circumcised by sharp rocks as they enter the land (Joshua 5; cf. Exodus 4:25). Cut by the rock, Israel becomes a fruitful people, raising godly seed, in a fruitful land.
Yahweh the Rock is Israel’s source of living water; in circumcision, the people of Yahweh, branded by a rock, become a priestly people, supplying a living stream for the nations.
