Midrash sur Job 38:6

On the first day He took a lump of snow from beneath the Throne of Glory and threw it on the face of the waters in the middle of the world and it became land as it says, “For He says to the snow, 'Be upon the earth'…” (Iyov 37:6) And He took the foundation stone and cast it onto the place of the Temple and the world was founded upon it as it says, “…or who laid its cornerstone?” (Iyov 38:6) He called to the land and it stood in its place in order that it not move back and forth like a ship on the high seas as it says, “…God, God the Lord, spoke and called to the earth…” (Tehillim 50:1) And since His light shined, it shined first on the land of Israel and from there illuminated the whole world as it says, “From Zion, the perfection of beauty, God appeared.” (Tehillim 50:2) How did He illuminate it? He donned His tallit and wrapped Himself in His light and lit up the world as it says, “[You] enwrap Yourself with light like a garment…” (Tehillim 104:2) All that day the waters covered the land and it was dissolving until He donned the garments of majesty and His glory was seen as it says, “The Lord has reigned; He has attired Himself with majesty…” (Tehillim 93:1) And He girded Himself with a belt of might and established it through His might as it says, “…He has girded Himself with might. The world also is established that it cannot be moved.” (ibid.)
