"Again, you have heard that it was told those who lived long ago, "You must not swear an oath falsely,' but, "You must fulfill your oaths to the Lord.'

but I -- I say to you, Love your enemies, bless those cursing you, do good to those hating you, and pray for those accusing you falsely, and persecuting you,

But he denied it before them all, saying, “I do not know what you are talking about.”
