Musar sobre Deuteronómio 6:16

“Do not try the Lord your God” (Deuteronomy 6:16). And we are warned with this that a man should not say, “I will make a trial with my service of charity [whether] the Lord will make my way successful; and I will test through the properness of my actions, whether my gold and silver will grow.” But the good man will not slacken from his toil in wisdom, knowledge and proper action when his path in the matter of his money and the rest of the goods of the body are not successful. And our Rabbis, may their memory be blessed, said (Taanit 9a) that only with tithes of the storehouse is testing [God] permitted, as it is stated (Malachi 3:10) “Bring the full tithe into the storehouse, and let there be food in My House, and thus put Me to the test.” King Solomon, peace be upon him, said (Proverbs 3:9-10), “Honor the Lord with your wealth, with the first of all your produce. And your barns will be filled with grain, [etc.].” Its explanation is, if you do not have like this - to be filled with grain when you give from your wealth and from the first of all your produce - but you are rather seized by days of poverty, “Do not reject the discipline of the Lord” (Proverbs 3:11), and know that this is also for your good. “For whom the Lord loves, He rebukes” (Proverbs 3:12), to do good for him in his end; that the reward in this world and his honor be exchanged for the good that is hidden and continues forever.

And concerning one who deliberately places himself in danger and says, "I trust in the Lord, may He be Blessed," about him it is said : "But the fool behaves overbearingly and is confident" (Prov. 14:16). And the Torah has warned us concerning this as it is written : "You shall not try the Lord your God" (Deut. 6:16). And he who places himself in danger and kills himself through his folly, his punishment is greater than that of a man who kills others.
