A.T. Robertson Commentary Luke 10:37

"And he said, He that showed mercy on him. And Jesus said unto him, Go, and do thou likewise." — Luke 10:37 (ASV)

On him (μετ' αυτου). With him, more exactly. The lawyer saw the point and gave the correct answer, but he gulped at the word "Samaritan" and refused to say that.

Do thou (συ ποιε). Emphasis on "thou." Would this Jewish lawyer act the neighbour to a Samaritan? This parable of the Good Samaritan has built the world's hospitals and, if understood and practised, will remove race prejudice, national hatred and war, class jealousy.
