Our tradition, as always, has some fascinating ideas. to Bereshit Rabbah, a classic collection of rabbinic interpretations of the Book of Genesis. Specifically, we're looking at the fourth section, which grapples with the creation of the shamayim – the heavens.
The verse we're unpacking is Genesis 1:8: “God called the firmament heavens. It was evening and it was morning, a second day.” Now, what does "heavens" – shamayim in Hebrew – actually mean here?
Rav, a prominent Babylonian sage, offers a striking thought: shamayim hints at the presence of both esh (fire) and mayim (water). Fire and water – seemingly opposite elements – combined in the very fabric of the heavens! Rabbi Abba bar Kahana, quoting Rav, elaborates: The Holy One, blessed be He, took fire and water and integrated them, creating the heavens. A beautiful image of harmony born from contrast, isn’t it?
But there's more! The rabbis weren't content with just the physical composition of the heavens. They also explored its moral significance. The text suggests a play on words: shamayim can also be read as shamim, meaning "they assess." The heavens, in this view, are constantly evaluating our actions. If we are righteous, "the heavens declare his righteousness," as Psalm 97:6 tells us. But if we stray, "the heavens reveal his iniquity," as we find in Job 20:27. It's a powerful reminder that we are always being watched, judged not by some distant deity, but by the very cosmos itself.
And the wonder of it all! Another interpretation suggests that shamayim evokes mishtomem – astonishment. The creations themselves marvel at the heavens, asking, “Of what do they consist? Are they of fire, are they of water? It is a wonder!” Rabbi Pinhas, citing Rabbi Levi, brings in Psalm 104:3 to settle the debate: "He roofs His upper chambers with water," suggesting that the heavens are fundamentally made of water.
The text doesn't stop there. It proposes that shamayim also alludes to samim – dyes. Just as dyes come in a variety of colors – green, red, black, white – so too do the heavens appear in different hues at different times. A poetic way to describe the ever-changing sky!
Then comes Rabbi Yitzchak with another clever interpretation: Shamayim – sa mayim, "bearing water." He uses the analogy of milk in a bowl. Initially loose, it congeals when a drop of rennet is added. Similarly, Job 26:11 speaks of the "pillars [amudei] of heaven" being loose until God added his "rennet," solidifying them. This, Rav adds, happened on the second day of creation. They were moist on the first day and congealed on the second.
So, what do we take away from all this? The creation of the heavens isn't just a simple act of divine construction. It's a complex, multifaceted process involving fire and water, judgment and wonder, and a touch of divine chemistry. It's a reminder that the world around us is filled with layers of meaning, waiting to be uncovered. And maybe, just maybe, the next time you look up at the sky, you'll see not just a blue expanse, but a testament to the endless creativity and wisdom embedded in creation itself.
