No crime shall it be in the blind, or in the lame, or in the sick, to eat at your tables: or in yourselves, if ye eat in your own houses, or in the houses of your fathers, or of your mothers, or of your brothers, or of your sisters, or of your uncles on the father's side, or of your aunts on the father's side, or of your uncles on the mother's side, or of your aunts on the mother's side, or in those of which ye possess the keys, or in the house of your friend. No blame shall attach to you whether ye eat together or apart. And when ye enter houses, salute one another with a good and blessed greeting as from God. Thus doth God make clear to you His signs, that haply ye may comprehend them.
