Musar su Proverbi 22:29

And King Shlomo, peace be unto him, said: "Do you see a man quick in his work? He shall stand before kings; he shall not stand before lowly men" (Mishlei 22:29).

For their matters are very similar. There is no difference between them except that Zeal is for the positive commandments while Watchfulness is for the negative commandments.

See how removed the lazy man is from good qualities, how worthless as a messenger. He is like vinegar, which is bad for the teeth, as it is said, "As vinegar to the teeth, and as smoke to the eyes, so is the sluggard to them that send him" (Prov. 10:26). And it is said, "The desire of the slothful killeth him; for his hands refuse to labour" (Prov. 21:25). And it is said, "The sluggard is wiser in his own eyes than seven men that give wise answer" (Prov. 26:16). The meaning of this verse is as follows : There was a king who had many runners and messagers, and they all did his bidding, and they would report to the king when they returned from their errands. But one of the servants of the king was a lazy man, and he cunningly said, "I am ill!" And he rested and ate from the king's table. When he saw his companions, weary from the exertions of the journey, he considered himself wiser than all of them. But this is folly, for it is written, "Seest thou a man diligent in his business? He shall stand before kings" (Prov. 22:29). Here, too, the king rewards those who did his bidding.
