Matthew 5:11-13 New Revised Standard Version (NRSV)
11 “Blessed are you when people revile you and persecute you and utter all kinds of evil against you falsely[a] on my account. 12 Rejoice and be glad, for your reward is great in heaven, for in the same way they persecuted the prophets who were before you.

13 “You are the salt of the earth; but if salt has lost its taste, how can its saltiness be restored? It is no longer good for anything, but is thrown out and trampled under foot.
