Pensée juive sur Les Proverbes 10:3

If a man strengthens himself in the service of G-d, resolves to fear Him, trusts in Him for his religious and secular matters, steers away from reprehensible things (such as anger or arrogance - PL), strives for the good midot (character traits), does not rebel in prosperity nor turn towards leisure, is not enticed by the evil inclination, nor seduced by the witchery of this world - the burden of exerting himself in the means to a livelihood will be removed from him, since the two reasons mentioned above no longer apply to him, namely, to test him on his choice and to protect him from rebelling during prosperity. His livelihood will come to him without strain (of the heart - PL) or toil (of the limbs - PL), according to his needs, as written "G-d will not bring hunger to the righteous" (Mishlei 10:3).

(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)
