Translation:Shulchan Aruch/Choshen Mishpat/426

Paragraph 1- If one sees another drowning at sea, or with bandits or a vicious animal attacking him, and he has the ability to rescue the victim himself or hire others to rescue, and he does not do so, or if he saw idolaters or informers creating an evil plot against him or setting a trap and he does not have the victim hear about it nor inform the victim, or if he knew of an idolater or oppressor that was coming after him and he had the ability to appease him and remove the personal issues he had against the victim but he did not do so, or anything similar, he has violated “you shall not stand idly by the blood of your friend.”
