Psalms 74:15
15 Thou didst cleave the fountain and the flood: thou driedst up mightye rivers.
Psa. 74:15. "Flood." God, in dividing Jordan, did not only divide the water that ordinarily belonged to the river, or the water which came from its fountains, but also the extraordinary additional waters by the great rains a little before harvest. So God cleaved both the fountain - i.e., the fountain water - and the flood.
Psa. 78:43
