Matthew Poole and continuators on Genesis 1:9

9. ¶ And God said, Let the Waters under the Heaven be gathered together unto one place, and let the dry-land appear : And it was so.

Both the great Abyss, or deep of Water which is shut up in the bowels of the Earth, Gen. 7. 11. Ps. 24. 2. and 33. 7. and 136. 6. as also the Sea and Rivers all which are here said to be gathered together into one place, because of their Communication and mixture one with another.

For hitherto it was covered with Water, v. 2. 2 Pet. 3. 5.
