From Jesus’ Sermon on the Mountain
On Impurity
“You have heard that it was said—
‘Thou shalt not commit adultery.’
I, however, say to you that any one who looks at a woman with an impure intention has already committed adultery with her in his heart. If your right eye is a snare to you, take it out and throw it away. It would be best for you to lose one part of your body, and not to have the whole of it thrown into the Pit. And, if your right hand is a snare to you, cut it off and throw it away. It would be best for you to lose one part of your body, and not to have the whole of it go down to the Pit.
On Divorce
“It was also said—
‘Let any one who divorces his wife serve her with a notice of separation.’
I, however, say to you that any one who divorces his wife, except on the ground of her unchastity, leads to her committing adultery; while any one who marries her after her divorce is guilty of adultery.
On Oaths
“Again, you have heard that to our ancestors it was said—
‘Thou shalt not break an oath, but thou shalt keep thins oaths as a debt due to the Lord.’
I, however, say to you that you must not swear at all, either by Heaven, since that is God’s throne, or by the earth, since that is his footstool, or by Jerusalem, since that is the city of the Great King. Nor should you swear by your head, since you cannot make a single hair either white or black. Let your words be simply “Yes” or “No”; anything beyond this comes from what is wrong.
On Revenge
“You have heard that it was said—
‘An eye for an eye and a tooth for a tooth.’
I, however, say to you that you must not resist wrong; but, if any one strikes you on the right cheek, turn the other to him also; and, when any one wants to go to law with you, to take your coat, let him have your cloak as well; and, if any one compels you to go one mile, go two miles with him. Give to him who asks of you, and, from him who wants to borrow from you, do not turn away.”
—Matthew.
Who shall ascend into the hill of the Lord? or who shall stand in his holy place?
He that hath clean hands and a pure heart.
—Psalms.
