Exodus 22:27-23:5

You shall not revile God, nor put a curse upon a chieftain among your people. You shall not put off the skimming of the first yield of your vats. You shall give Me the first-born among your sons. You shall do the same with your cattle and your flocks: seven days it shall remain with its mother; on the eighth day you shall give it to Me. You shall be holy people to Me: you must not eat flesh torn by beasts in the field; you shall cast it to the dogs. You must not carry false rumors; you shall not join hands with the guilty to act as a malicious witness: You shall neither side with the mighty to do wrong--you shall not give perverse testimony in a dispute so as to pervert it in favor of the mighty--nor shall you show deference to a poor man in his dispute. When you encounter your enemy's ox or ass wandering, you must take it back to him. When you see the ass of your enemy lying under its burden and would refrain from raising it, you must nevertheless raise it with him.
