“When an Israelite and a Gentile have a lawsuit before thee, if thou canst, acquit the former according to the laws of Israel, and tell the latter such is our law; if thou canst get him off in accordance with Gentile law, do so, and say to the plaintiff such is your law; but if he cannot be acquitted according to either law, then bring forward adroit pretexts and secure his acquittal. These are the words of Rabbi Ishmael.”
