Rabbi Judah answered, " Let me relate to thee a parable. A king had an orchard of fine figs, which he prized most highly. That the fruit might not be stolen or abused, he placed two watchers in the orchard, and that they themselves might not be tempted to partake of the fruit, he chose one of them a blind man, and the other one lame. But lo, when they were in the orchard, the lame man said to his companion, (I see very fine figs; they are luscious and tempting; carry me to the tree, that we may both partake of them.*
