John Gill Commentary Luke 6:31

"And as ye would that men should do to you, do ye also to them likewise." — Luke 6:31 (ASV)

And as you would that men should do to you In matters of justice and beneficence were they in your case, and you in theirs;

do you also to them likewise : a golden rule this, agreeably to the light of nature, and divine revelation, and is the sum and substance of the law and prophets; (See Gill on Matthew 7:12).
