Commandment five commands us not to hurt or harm our neighbor in his body. The thieves in the Good Samaritan parable come to mind. They pounded on him and left him naked and half dead. Threw him out as a piece of human garbage after they were done with what they could take from him. We get that keeping of the commandment. Bad idea. Don't pound on people.
But Jesus pushes further with the behavior of the priest and the levite - both of whom cross to the other side of the road. How many times have we walked that way with them? And why? Fear. Is it a set up? What will happen if I get involved? *I* could get hurt.
Along comes the Good Samaritan. He not only didn't hurt or harm us in our body, but He helped and supported us in every physical need. Is there a physical need greater than release from death? And He's come to provide that. Did it hurt Him? Sure did. Cross and all that. Yet thereby He pardons our sins (though we regard him as the enemy!) and He provides for our care and nurture in the Church and He grants us the healing that lands in resurrection along with Him.
This is the life He reaches us: a life without fear! What's to fear? Our sins, forgiven by His blood. Our death, destroy by His death. Our eternal life, assured. And His heart of compassion toward the man, woman, child in need - He reaches us as our own.
