Midrash su Salmi 136:11

Before the waters were gathered together the depths were created. These are the depths which are beneath the earth; for the earth is spread upon the water like a ship which floats in the midst of the sea, so likewise is the earth spread out over the water, as it is said, "To him that spread forth the earth above the waters…" (Ps. 136:6). He opened an entrance to the Garden of Eden because thence were planted upon the face of all the earth all kinds of trees yielding fruit according to their kind, and all kinds of herbs and grass thereof, and in them (was seed), as it is said, "Wherein is the seed thereof, upon the earth" (Gen. 1:11). He prepared a table for the creatures whilst as yet they were not created, as it is said, "Thou preparest a table before me" (Ps. 23:5). All the fountains arise from the depths to give water to all creatures.
