'Channels' in the Bible

Then the channels of the sea could be seen, and the foundations of the earth were uncovered because of your rebuke, LORD, because of the blast from the breath of your nostrils.

"It's the king of Assyria and all of his arrogance! He will rise over all of the river's channels and run over all of its banks. He will sweep on into Judah, overflowing as he passes through, like flood waters reaching up to a person's neck. His outstretched wings will flow as wide as your land, O Immanuel!"

Abundant water made it great, Subterranean rivers made it grow. Rivers surrounded the area where it had been planted, and water channels nourished all the trees in the fields.

So I said, "I have been watching and look! there is a menorah made completely of gold with a bowl on top of it. And there are seven lights on it, along with seven feeder channels to the lamps, which are also on top of it. Two olive trees are near it, one on the right side of the bowl and one on the left."

I also asked him a second question: "What are these two olive branches on either side of the two golden feeder channels that carry the golden oil to the seven lights?"
