so the particle is used in Ps 1:3. Some have thought that the first earth, which Peter says was standing in the water, and out of the water, 2Pe 3:5, was made in the form of an egg, and that the waters were under the earth, and the earth was as a crust or shell over them, until the deluge came; and this crust then broke in, and formed the sea; and so it was literally true, that the earth was founded upon, or over the waters;and established it upon the floods; the floods of the seas, or rivers of water running to and fro in it: this shows the ground and foundation of Christ's right and claim to the earth, and all that is in it; which is not by reason of his father's gift to him as Mediator, but by virtue of his concern in creation, the world, and all things in it, being made and established by him; in him do all things consist, Col 1:16.
