Noach: Rainbow Covenant

יהוה smelled the pleasing odor, and יהוה resolved: “Never again will I doom the earth because of humankind, since the devisings of the human mind are evil from youth; nor will I ever again destroy every living being, as I have done.
So long as the earth endures,
Seedtime and harvest,
Cold and heat,
Summer and winter,
Day and night
Shall not cease.” God blessed Noah and his sons, and said to them, “Be fertile and increase, and fill the earth. The fear and the dread of you shall be upon all the beasts of the earth and upon all the birds of the sky—everything with which the earth is astir—and upon all the fish of the sea; they are given into your hand. Every creature that lives shall be yours to eat; as with the green grasses, I give you all these. You must not, however, eat flesh with its life-blood in it. But for your own life-blood I will require a reckoning: I will require it of every beast; of humankind, too, will I require a reckoning for human life, of everyone for each other!
Whoever sheds human blood,
By human [hands] shall that one’s blood be shed;
For in the image of God
Was humankind made. Be fertile, then, and increase; abound on the earth and increase on it.” And God said to Noah and to his sons with him, “I now establish My covenant with you and your offspring to come, and with every living thing that is with you—birds, cattle, and every wild beast as well—all that have come out of the ark, every living thing on earth. I will maintain My covenant with you: never again shall all flesh be cut off by the waters of a flood, and never again shall there be a flood to destroy the earth.” God further said, “This is the sign that I set for the covenant between Me and you, and every living creature with you, for all ages to come. I have set My bow in the clouds, and it shall serve as a sign of the covenant between Me and the earth. When I bring clouds over the earth, and the bow appears in the clouds, I will remember My covenant between Me and you and every living creature among all flesh, so that the waters shall never again become a flood to destroy all flesh. When the bow is in the clouds, I will see it and remember the everlasting covenant between God and all living creatures, all flesh that is on earth. That,” God said to Noah, “shall be the sign of the covenant that I have established between Me and all flesh that is on earth.”

לא אסף… ולא אסף I WILL NEVER AGAIN … NEITHER WILL I EVER AGAIN — He repeated the expression that it might serve as a solemn oath, and it is to this that the text (Isaiah 54:9) refers: “For as I have sworn that the waters of Noah [will never again pass over the earth]”. We, however, do not find any explicit oath regarding this, but this passage in which He repeated these words, which may be regarded as an oath. Thus do our Sages explain in Treatise Shevuot 36a.

עוד כל ימי הארץ זרע וקציר, וקור וחום, וקיץ וחורף, ויום ולילה, לא ישבתו; nature will not cease to function dependably as it had prior to the deluge. The sun will orbit predictably, its orbit will be subject to calculation in advance, so will be its position relative to other phenomena in the sky. All the time periods mentioned in this verse will somehow be related to the position of the sun at different times during the year. It would be different from before the deluge. Whereas prior to the deluge the sun had remained at a fixed distance relative to the earth all year round, its orbit being circular, resulting in eternal spring in the populated parts of the earth, now there would be all these changes, though at predetermined intervals, resulting in alternating seasons of relative warmth and cold due to the elliptical nature of the sun’s orbit [Although the author lived approximately at the time of Copernicus having determined that the earth moves around the sun instead of being the center of our galaxy, the basic concept even according to the ancient world view does not invalidate the author’s description of antediluvian and postdiluvian climatic conditions. Ed.. כל ימי הארץ, until such time as G’d would correct this deterioration in living conditions on earth due to the effect of the deluge. This “correction” is what the prophet Isaiah 66,22 had in mind when he spoke of the הארץ החדשה אשר אני עושה, “the new earth which I am going to make.” In that future foreseen by the prophet, the sun will once more orbit like a circle instead of like an ellipsis, a configuration responsible for the uneven temperatures on earth during different parts of the year. At that time, the whole vegetation on earth will undergo an upgrading, the curse earth experienced both after Adam’s sin and after Kayin’s murder of his brother Hevel being lifted. Conditions of length of human life will revert to what they had been before the deluge, as the prophet said that a נער, a youth, if he dies at a hundred years old will be considered as having died in his adolescence and more verses there describing this future. This is also what David referred to in Psalms 65,9 מוצאי בוקר וערב תרנין, “You make the lands of sunrise and sunset shout for joy.”

We still need to supply a reason why the verse once mentions the curse before the word עוד, i.e. לא אוסיף לקלל עוד, whereas in the second half of the verse the sequence is ולא אוסיף עוד להכות, the word עוד already appearing before the predicate of the sentence. The reason is that a curse directed at the earth already has a past history, i.e. earth has been cursed before and the effects of that curse still existed. When G'd curses living creatures there is no noticeable effect of any previous curse as any living creatures that had been cursed or smitten prior to the present curse were already dead and as if they had never existed. Our verse incorporates this nuance. It reminds us that the earth was still suffering from the effect of previous curses.
