Derashot HaRan
But all of this, though it be confirmed by nature and substantiated by the words of our sages of blessed memory, seems exceedingly strange upon closer scrutiny, at complete variance with the premise of the Book of Ecclesiastes, in the beginning of which it is laid down that all things beneath the moon are vain and ephemeral, this assertion being subsequently borne out by proofs, the principle upon which they all revolve being that since these composites were all compounded from elements that are subject to movement and change, it must necessarily follow that the composites themselves partake of these characteristics. For there he [Solomon] also mentions all of the elements and states that none of them possesses permanence and endurance except the basest of them, the element of earth, as it is written (Ecclesiastes 1:4): "…but the earth abides forever." And then he goes on to explain that the three other elements, which, in combination could conceivably contribute to perfection, especially to that of the animal kingdom, and, most specifically to man — in that the properties upon which his existence depends are moisture and warmth, all three elements possessing at least one of these properties, so that it should follow that all of these should impart to the man that is compounded of them permanence and endurance — [though one might reason thus] he goes on to state that this is impossible in that each one of the elements is subject to change. He begins with the element of fire, alluding to it by mention of its origin (Ibid 5): "The sun rises," continues with the element of air, saying (Ibid 6): "Round and round goes the wind," and concludes with the element of water, saying (Ibid 7): "All the rivers run into the sea."
Yesod Mora VeSod HaTorah
In the words of our sages, there are many statements that require evidence and interpretation, such as in Pirkei Avot (3:4) "One who is awake at night" [referring to studying Torah at night], and in Pesachim (111a) "And [he] drank water" [referring to the wisdom of measurements]. And the matter of the letter of the daughter of the voice [the Shekhinah] is derived from the laws of the constellations. And the matter of the moon and its relationship with the sun is derived from the wisdom of the constellations. Similarly, many things in the Scriptures require interpretation, as mentioned by Kohelet regarding the four elements, which are the heavens, the earth, the wind, and the dust. It is written (Kohelet 1:5) "And the sun rises and the sun sets" corresponding to the heavens, (Kohelet 1:4) "And the earth stands forever," (Kohelet 1:6) "And the wind goes round and round," and it does not come to an end, (Kohelet 1:7) "All the rivers flow into the sea," and these four are mentioned in the portion of Bereishit (Genesis 1:1) "The heavens and the earth," (Genesis 1:2) "And the spirit of God hovered over the waters." And similarly, in Isaiah (40:12), "Who measured the waters in the hollow of His hand and marked off the heavens with a span, and calculated the dust of the earth in a measure," and in Psalms (104:2), "He stretches out the heavens like a curtain, He lays the beams of His chambers on the waters," and His angels are the winds that roam over the water. And likewise, in Psalms (33:7), "He gathers the waters of the sea together as a heap; He sets the deeps in storehouses. Let all the earth fear the Lord; let all the inhabitants of the world stand in awe of Him." And similarly, it is mentioned in Psalms (33:6) regarding the word of God, "By the word of the Lord the heavens were made, and all their host by the breath of His mouth." And similarly (Job 28:25), "To establish a weight for the wind and apportion the waters by measure." For He looks to the ends of the earth and sees under the whole heavens. And thus it is written (Proverbs 30:4), "Who has ascended to heaven and come down? Who has gathered the wind in His fists? Who has wrapped up the waters in His garment? Who has established all the ends of the earth? What is His name, and what is His Son's name? Surely you know!" And thus it is written elsewhere (Job 38:18), "Have you comprehended the expanse of the earth? Declare, if you know all this!" And all is prepared for the understanding one. And many such things are mentioned at the end of the Book of Psalms, as fire and hail, snow and mist, stormy wind fulfilling His word. And thus the waters are above the heavens, and how the luminaries and the stars are in one expanse, and all is true. And the sages of the Talmud in our generation are diverse in their approaches. There are those who delve into matters of prohibition and permission, and there are those who possess knowledge of the Midrashim, and they too provide new insights and seek meaning for every word, whether surplus or lacking. And now, let me state a general principle: Know that the prophets do not guard the words themselves in their years; rather, they guard the meanings alone, which are the essence, as in the words of Eliezer (Genesis 24), "The Lord, before whom I have walked, will send His angel with you." And Isaac said to Esau (Genesis 27), "So that my soul may bless you before I die." And Rebekah said (Genesis 27), "So that I may bless you before the Lord before my death." And in the dream (Genesis 41), "Handsome in appearance and robust in form," and in the interpretation, it is not stated thus, but to Balaam (Numbers 22), it is said, "You shall not curse them at all, and indeed, you shall bless them." And in the words of Moses (Numbers 21), "And he sent messengers to Sihon, saying, 'Let me pass through your land; I will not turn aside into field or vineyard.'" But Moses changed it and said, "We will not pass through the field." And it is written (Exodus 32), "Now, leave Me alone, and let My anger flare up against them, that I may consume them." But Moses changed it and said, "Turn from Your burning anger and relent from this disaster against Your people." And there are many such instances. And behold, in the Ten Commandments (Exodus 20), "Remember" (Deuteronomy 5), "Observe" (Exodus 20), "You shall not covet" (Deuteronomy 5), "You shall not desire" (Exodus 20), "And any false oath" (Deuteronomy 5), "And any vain oath." The letters 'vav' (ו) in "Avnei" (אבני) are missing, and Moses changed it to have a 'vav' (ו). Also, "You shall not commit adultery" - this is an addition and a rebuke, and the intelligent one will understand.
Guide for the Perplexed
The following are the words that refer to the indestructibility of the Universe: “And the earth remaineth for ever.” And those who do not agree with me as regards the above distinction [between the indestructibility and the Eternity of the Universe], are compelled to explain the term le-‘olam (lit., “for ever”), to mean “the time fixed for the existence of the earth.” Similarly they explain the words of God, “Yet all the days of the earth” (Gen. 8:22) to signify the days fixed for its existence. But I wonder how they would explain the words of David: “He laid the foundations of the earth, that it should not be moved for ever” (Ps. 104:5). If they maintain here also that the term le-‘olam va-‘ed (lit. “for ever”) does not imply perpetuity, they must come to the conclusion that God exists only for a fixed period, since the same term is employed in describing the perpetuity of God, “The Lord will reign (le-‘olam) for ever” (Exod. 15:18, or Ps. 10:16). We must, however, bear in mind that olam only signifies perpetuity when it is combined with ad: it makes no difference whether ‘ad follows, as in ‘olam va-‘ed, or whether it precedes, as in ‘ad ‘olam. The words of Solomon which only contain the word le-‘olam, have therefore less force than the words of David, who uses the term olam va-‘ed. David has also in other passages clearly spoken of the incorruptibility of the heavens, the perpetuity and immutability of their laws, and of all the heavenly beings. He says, “Praise ye the Lord from the heavens, etc. For He commanded, and they were created. He hath also stablished them for ever and ever; he hath made a decree which shall not pass” (Ps. 148:1-6); that is to say, there will never be a change in the decrees which God made, or in the sources of the properties of the heavens and the earth, which the Psalmist has mentioned before. But he distinctly states that they have been created. For he says, “He hath commanded, and they were created.” Jeremiah (xxxi. 35) likewise says, “He giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night,” etc. “If these ordinances depart from before me, saith the Lord, then the seed of Israel also shall cease from being a nation before me for ever.” He thus declares, that these decrees will never be removed, although they had a beginning. We therefore find this idea, when we search for it, expressed not only by Solomon but also by others. Solomon himself has stated that these works of God, the Universe, and all that is contained in it, remain with their properties for ever, although they have been created. For he says, “Whatsoever God doeth, it shall be for ever: nothing can be put to it, nor anything taken away from it” (Eccles. 3:14). He declares in these words that the world has been created by God and remains for ever. He adds the reason for it by saying, “Nothing can be put to it, nor anything taken from it;” for this is the reason for the perpetuity, as if he meant to say that things are changed in order to supply that which is wanting, or in order to take away what is superfluous. The works of God being most perfect, admitting no addition or deduction, must remain the same for ever. It is impossible that anything should exist that could cause a change in them. In the conclusion of the verse, Solomon, as it were describes the purpose of exceptions from the laws of Nature, or an excuse for changes in them, when he says, “And God doeth it (viz., He performs miracles) that men should fear before him.” The words which follow, “That which hath been is now; and that which is to be hath already been, and God seeketh that which is pursued,” contain the idea that God desires the perpetuity and continuity of the Universe.
