Yahweh as the creator of earth (Ps 104:5-104:9)

“You set the earth on its foundations.

Thus it shall never be shaken.

You cover it with the deep

As with a garment.

The waters stood above the mountains.

At your rebuke

They fled.

At the sound of your thunder

They took to flight.

They rose up to the mountains.

They ran down to the valleys.

They all went to the place that you appointed for them.

You set a boundary.

They may not pass this boundary.

Thus the waters might not again cover the earth.”

The earth had foundations like any building in a very static way. There was no hint of a round world in this flat world concept of the earth. However, they did seem to understand that the solid earth came from the waters. At the command of Yahweh, the waters receded, much like at the time of Noah in Genesis, chapters 6-10. The thunder served as the voice of Yahweh telling the waters to recede, which they did. Then the earth was formed as the mountains rose and the valley sunk, all due to the water that had been there. Everything took its place as it was appointed by Yahweh. Yahweh put boundaries on the waters so that they would never again cover the earth. This was the victory of Yahweh over the chaos of the waters.
