Tradidit arcano quaecunque volumine Moses:
Non monstrare vias eadem nisi sacra colenti,
Quaesitum ad fontem solos deducere verpos.
[Juvenal, Sat. xiv. 102.]
The letter of this law is not to be found in the present volume of Moses. But the wise, the humane Maimonides openly teaches that, if an idolater fall into the water, a Jew ought not to save him from instant death. See Basnage, Histoire des Juifs, 1. vi. c. 28 [1. v. c. 24].
