Matthew 5:28, 34, 44

but I say to you that everyone who [so much as] looks at a woman with lust for her has already committed adultery with her in his heart.

But I say to you, do not make an oath at all, either by heaven, for it is the throne of God

But I say to you, love [that is, unselfishly seek the best or higher good for] your enemies and pray for those who persecute you, [Prov 25:21, 22]
