Thematic Bible: Even on the sabbath day

But that is why Moses has instituted circumcision among you- -not, indeed, that it began with him, but with our ancestors--and that is why you circumcise even on a Sabbath. When a man receives circumcision on a Sabbath to prevent the Law of Moses from being broken, how can you be angry with me for making a man sound and well on a Sabbath?
