Responsa zu Tehillim 134:2

They responded to the first question: "Lift your hands to the sacred!" (Psalms 134:2) Namely, wash your hands whenever you want to speak sacred words or study Torah. "And bless God!" (ibid.) - with the blessing instituted for washing hands. As for the second question, they responded: Do you not know that four need to give thanks (Berachot 54b:12), and this includes one who was sick. And none are more sick than such a person [who relieves themself], as it says (Isaiah 51:14): "Quickly the crouching one is freed."²cf. Rashi on Isaiah 51:14

They responded: "My son, do not envy sinners in your heart," (Proverbs 23:15-17) "Happy are those who abide by His laws," (Psalms 119:2) "Lift your hands towards the sacred," (Psalms 134:2) "Blessed is God day by day," (Psalms 68:20) "Test Me by this, if I do not pour down blessings upon you ceaselessly." (Malachi 3:10). Some time later, they responded: "Any passage stated and then repeated is only repeated to teach something new." (Sotah 3b:2) - and the sages did not come to take away, but only to add and to encourage. "One who is vigilant is praiseworthy," (Yoma 84b:8) "And then you shall find delight in God," (Isaiah 58:14) "And He shall grant you the desires of your heart." (Psalms 37:4) ^*Perhaps this answer follows the line of reasoning of Eleazar of Worms (Sefer Haroke'ach 369, quoted by Beit Yosef Orach Chaim 38), whereby the meaning of the sentence 'One who wears tefillin is like one who reads from the Torah, etc.' is understood to give those who do both the reward of both commandments.
