Jesus said this?? Are you kidding?

[MatthewG]

“but I — I say to you, not to swear at all; neither by the heaven, because it is the throne of God, nor by the earth, because it is His footstool, nor by Jerusalem, because it is a city of a great king, nor by thy head mayest thou swear, because thou art not able one hair to make white or black; but let your word be, Yes, Yes, No, No, and that which is more than these is of the evil. ‘Ye heard that it was said: Eye for eye, and tooth for tooth; but I — I say to you, not to resist the evil, but whoever shall slap thee on thy right cheek, turn to him also the other; and whoever is willing to take thee to law, and thy coat to take — suffer to him also the cloak. ‘And whoever shall impress thee one mile, go with him two, to him who is asking of thee be giving, and him who is willing to borrow from thee thou mayest not turn away. ‘Ye heard that it was said: Thou shalt love thy neighbour, and shalt hate thine enemy; 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, that ye may be sons of your Father in the heavens, because His sun He doth cause to rise on evil and good, and He doth send rain on righteous and unrighteous. ‘For, if ye may love those loving you, what reward have ye? do not also the taxgatherers the same? and if ye may salute your brethren only, what do ye abundant? do not also the taxgatherers so? ye shall therefore be perfect, as your Father who [is] in the heavens is perfect.”

A lot is being said there, basically in modern day terms, dont lie, do good to others including what would be considered enemies because God allows them to exist. Imitate God, as did our prime exemplar Jesus did.
