ייִדישער מחשבֿה אויף משלי 2:5

It goes without saying that this applies to the study of natural science, including the study of inanimate objects, plants and living creatures, minerals and the earth, and the study of mathematics, including arithmetic, measurement, and astronomy, etc., which are tied to the laws of the Torah, such as the rules of mixed species, determining the calendar, signs of kosher and non-kosher animals, etc. Those who turn a blind eye from these topics are referred to by Isaiah: “They regard not the work of the Lord; neither do they see his handiwork.” (5:12). These are all included in the saying “Then you will understand reverence for God” (Proverbs 2:5). Because of these studies, a person will understand the greatness of God’s strength, God’s honor will be increased in his heart and he will revere God. We do not need to elaborate further on this topic, since earlier authors have written about it at length. These matters gladden the heart, for God loves truth, and it is appropriate for us to do the right and proper thing.
