ייִדישער מחשבֿה אויף תהילים 34:11

If he places his trust in his wisdom and tactics, physical strength and industriousness - he will toil for nothing, his strength will weaken, and his tactics will fall short of accomplishing his desire, as written "He traps the wise with their own cunning" (Iyov 5:13) , and "I returned and saw under the sun, that the race does not belong to the swift, nor the war to the mighty; neither do the wise have bread, [nor do the understanding have wealth, nor the knowledgeable, favor for time and chance happens to them all]" (Koheles 9:11), and "Young lions suffer want and are hungry, but those who seek the L-ord lack no good" (Tehilim 34:11).

(1) The alchemist requires special materials to perform his operation, without which he cannot do anything. These materials are not found at all times and in all places. But for one who trusts in G-d, his sustenance is assured and can come through any means of all the means of the world, as written "[And He fed you with manna, which you knew not, neither did your fathers know]; That He might make known to you that man does not live by bread alone..." (Devarim 8:3). For at no time and in no place are the means of obtaining his livelihood withheld from him, as you know already from the story of Eliyahu and the ravens, or with the widow and the cakes and water (Melachim 17:9), or the story of Ovadia with the prophets, where he said "I hid among the prophets of G-d, 100 men, 50 in each cave, and I fed them bread and water" (Melachim 18:13) , and "Young lions suffer want and are hungry, but those who seek the L-ord lack no good" (Tehilim 34:11), and "Fear the L-ord, His holy ones; for there is no want to those who fear Him" (Tehilim 34:10).

(4) The alchemist must either prepare one large quantity of gold and silver for long term needs or must prepare small batches for short term needs. If he prepares a large quantity, all his days he will fear for his life that perhaps all the gold and silver will be lost in any number of ways (and he will be left penniless), and his heart will never quiet, nor will his mind be at peace due to fear of the king and of the people (finding his big stash of gold).If he makes small batches for short term use, it is possible that he will not successfully perform the procedure at a time of great need, due to a failure in one of the means. But one who trusts in G-d, has strong peace of mind that G-d will provide for him at any time He wishes and in any place, just like He sustains the fetus in its mother's womb or the chick inside an egg, which has no opening to enter anything from the outside, and birds in the air, or fish in the sea, and the tiny ant despite its weakness, while the mighty lion some days cannot obtain food, as written "Young lions suffer want and are hungry, but those who seek the L-ord lack no good" (Tehilim 34:11), and "The L-ord will not starve the soul of the righteous" (Mishlei 10:3), and "I have been young, and now am old; yet I not seen the righteous forsaken, nor his seed begging bread" (Tehilim 37:25)
