A.T. Robertson Commentary Luke 6:31

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

As ye would (καθως θελετε). In Mt 7:12 the Golden Rule begins: Παντα οσα εαν θελητε. Luke has "likewise" (ομοιως) where Matthew has ουτως. See on Matthew for discussion of the saying.
