I hate the vain watchmen. Gan Eden (Paradise) says "I hate the vain watchmen." And whom do I love? I love those who keep your commandments.
Gehinnom (Hell) says "I love the vain watchmen." And whom do I hate? I hate those who keep your commandments. (Proverbs 30:15) "The leech has two daughters, give, give." Gan Eden says, "Give me what is mine," and Gehinnom says, "Give me what is mine." (Another interpretation) "For my life is consumed with grief."
Rabbi Tanhuma bar Haiya says, "Four things weaken a person's strength: sin, the way (meaning a difficult or challenging path), fasting, and exile. Sin weakens my strength because of my sins, the way (Psalm 119:37) "Turn my eyes away from worthless things," weakens my strength, fasting (Psalm 109:24) "My knees give way from fasting," weakens my strength, and exile (Lamentations 1:14) "My strength is gone and so is my hope," weakens my strength."
Rabbi Tanhuma also said, "Even the narrowness is good for one who accepts it," as it is said (Psalm 38:11) "My heart pounds, my strength fails me, even the light has gone from my eyes."
