Rabbi Hama son of Rabbi Hanina taught that visiting the infirm (as God did in ) demonstrates one of God's attributes that humans should emulate. Rabbi Hama son of Rabbi Hanina asked what means in the text, "You shall walk after the Lord your God." How can a human being walk after God, when says, "Lord your God is a devouring fire"? Rabbi Hama son of Rabbi Hanina explained that the command to walk after God means to walk after the attributes of God. As God clothes the naked — for says, "And the Lord God made for Adam and for his wife coats of skin, and clothed them" — so should we also clothe the naked. God visited the sick — for says, "And the Lord appeared to him by the oaks of Mamre" (after Abraham was circumcised in ) — so should we also visit the sick. God comforted mourners — for says, "And it came to pass after the death of Abraham, that God blessed Isaac his son" — so should we also comfort mourners. God buried the dead — for says, "And He buried him in the valley" — so should we also bury the dead. Similarly, the Sifre on taught that to walk in God's ways means to be (in the words of ) "merciful and gracious."
