And Moses lifted up his hand,
And with his rod he smote the rock twice:
And the water came out abundantly:
And the congregation drank and their beasts also
- Deuteronomy 6:11
- OVID, Metamorphoses, XV
The face of places, and their forms decay;
And that is solid earth, that once was sea;
Seas, in their turn, retreating from the shore,
Make solid land, what ocean was before.
