John 13:17-18

If you know these things, you are blessed [happy and favored by God] if you put them into practice [and faithfully do them]. I am not speaking of all of you. I know whom I have chosen; but [this has happened] in order that the Scripture may be fulfilled: ‘HE WHO EATS MY BREAD HAS RAISED UP HIS HEEL AGAINST ME [as My enemy].’ [Ps 41:9]
