Matthew 25:36

I was sick, and ye visited me - Relieving the strangers, and visiting the sick, were in high estimation among the Jews. One of their sayings on this head is worthy of notice: "He who neglects to visit the sick is like him who has shed blood." That is, as he has neglected, when it was in his power, to preserve life, he is as guilty in the sight of the Lord as he is who has committed murder. See Kypke in loco.
