'Pools' in the Bible

And the LORD spake unto Moses, Say unto Aaron, Take thy rod, and stretch out thine hand upon the waters of Egypt, upon their streams, upon their rivers, and upon their ponds, and upon all their pools of water, that they may become blood; and that there may be blood throughout all the land of Egypt, both in vessels of wood, and in vessels of stone.

Who passing through the valley of Baca make it a well; the rain also filleth the pools.

I made me pools of water, to water therewith the wood that bringeth forth trees:

I will also make it a possession for the bittern, and pools of water: and I will sweep it with the besom of destruction, saith the LORD of hosts.

I will make waste mountains and hills, and dry up all their herbs; and I will make the rivers islands, and I will dry up the pools.
