Matthew 5:21-26

21 "You have heard that our fathers were told, `Do not murder,'l and that anyone who commits murder will be subject to judgment.
22 But I tell you that anyone who nurses anger against his brother will be subject to judgment; that whoever calls his brother, `You good-for-nothing!' will be brought before the Sanhedrin; that whoever says, `Fool!' incurs the penalty of burning in the fire of Gei-Hinnom!
23 So if you are offering your gift at the Temple altar and you remember there that your brother has something against you,
24 leave your gift where it is by the altar, and go, make peace with your brother. Then come back and offer your gift.
25 If someone sues you, come to terms with him quickly, while you and he are on the way to court; or he may hand you over to the judge, and the judge to the officer of the court, and you may be thrown in jail!
26 Yes indeed! I tell you, you will certainly not get out until you have paid the last penny.
