ציטירנדיקער פּירוש אויף תהילים 147:18

A spirit of comforting. Rashi is answering the question: If it was an actual wind, why is written afterwards, “And the water subsided”? On the contrary, it is written (Tehillim 147:8), “He blows His wind; water runs.” [I.e., wind does not calm the waters.] (Devek Tov) Alternatively, Rashi knows this because it says, “Over the earth.” How could a wind blow over the earth’s surface when the water covered the earth? But if it was “a spirit of comforting,” it is understandable. “Over the earth” then means, “On account of the matters of the earth.” In other words, for the sake of man who dwells on the earth.

And the earth was: This verse is connected to the one after it [as follows]: the earth at the beginning was such and such, and therefore, "God said, etc., etc."

And the wind of God was hovering: It is like its translation (Targum Onkelos), "A wind was blowing in front of God." And the understanding of "a wind of God" is a great and strong wind, as per "the wind of the Lord has blown upon it" (Isaiah 40:7); "He blows His wind, the waters flow" (Psalms 147:18); "You blew with Your wind" (Exodus 15:10); and like "the mountains of the Power" (Psalms 36:7) and "the Lord's flame" (Song of Songs 8:6).

Those who let gold run from the purse Heb. הַזָּלִים, an expression of (Ps. 146:18) “Water runs (יִזְּלוּ) .”

וישב [AND ABRAM] SCARED THEM AWAY — The word means “blowing upon a thing and making a thing fly away”, similar to (Psalms 147:18) יַשֵּׁב רוחו “He causeth His wind to blow”. It is a symbol that David, the son of Jesse, will wish to destroy them (the nations), but that he will not be permitted by God to do so until king Messiah comes (Pirkei D'Rabbi Eliezer 28).
