When Rabbi Shimon ben Yochai and his son, Rabbi Elazar, came out of
their cave on a Friday afternoon, they saw an old man hurrying along
with two bunches of myrtle in his hand. "What." said they, accosting
him, "dost thou want with these?" "To smell them in honor of the
Sabbath," was the reply. "Would not one bunch," they remarked, "be
enough for that purpose?" "Nay," the old man replied; "one is in honor
of 'Remember' (Exod. xxii. 28); and one in honor of 'Keep' (Deut. v.
8)." Thereupon Rabbi Shimon remarked to his son, "Behold how the
commandments are regarded by Israel!"
