Midrash su Isaia 38:16

R. Mair was accustomed to say that a man is bound to repeat a hundred blessings every day, as it is said (Deut. 10, 12) And now, Israel, what doth the Lord thy God require of thee. (Fol. 44) R. Shesheth said: "He who neglects to wear Tephilin (phylacteries) [every week-day], transgresses eight positive commandments; he who has no fringes on his garment transgresses five positive commandments. Any priest, who does not ascend [the stand] to pronounce the benediction transgresses three positive commandments. He who has no Mezuzah on his door-post transgresses two positive commandments, for the repeated word and ye shall write (Deut. 6,9; 11,20)." Resh Lakish said: "He who does not neglect to lay [every day] Tephilin will live long, as it is said (Is. 38, 16) O Lord, hy these things men live, and altogether therein is the life of my spirit. Wherefor recover Thou me, and make me to live."
