Musar su Salmi 147:10

Our Rabbis, may their memory be blessed, also said (Avodah Zarah 35a) that [the understanding of the verse] (Song of Songs 1:2), “For your love (dodekha) is better than wine” is [that] the statements of the Scribes are more beloved than the wine of the Torah. And we need to explain this also: You should surely know that the fear of God is the foundation of the commandments, as it is stated (Deuteronomy 10:12), “And now, O Israel, what does the Lord, your God, ask of you, other than to fear the Lord, your God.” And through this, God desires His creatures, as it is stated (Psalms 147:11), “The Lord desires those who fear Him.” And the ordinances of the Sages, and their decrees are the foundation of fear [of God]. For it makes a fence and a separation, lest the hand of a man [even] touch a Torah prohibition. [This is] like the owner of a field that makes a fence for his field since it is precious in his eyes. For he is afraid lest people enter it and it become a place to send oxen and for sheep to trample, like the matter that is stated (Leviticus 18:30), “You shall keep My guarding” - make a guarding for my guarding (Yevamot 21a). And is much carefulness, the fence and the separation from the prohibition not from the essence of fear? And one who augments his carefulness will reach great reward, like the matter that is stated, (Psalms 19:12), “Also Your servant pays them heed; in obeying them, there is much reward.” Therefore they said [that] the statements of the Scribes are more beloved than the wine of the Torah. For their fences and decrees are from the foundations of fear [of God]. And the reward for the commandment of fear is great in comparison to many [Torah] commandments, as it is the foundation for them. And the example for this thing is that one who is careful not to isolate himself with a woman, from his fear lest he stumble into iniquity - and like our Rabbis, may their memory be blessed, decreed - is this not because the light of the fear of God, may He be blessed, shone upon his soul?
