But because Moses gave you circumcision, you circumcise a boy on the Sabbath (not that it is from Moses, but from the patriarchs.) If a boy can be circumcised on the Sabbath so that the law of Moses will not be broken, why are you angry with Me for making the whole man well on the Sabbath?
This is My covenant with you and your descendants after you, which you are to keep: Every male among you must be circumcised. You are to circumcise the flesh of your foreskin, and this will be a sign of the covenant between Me and you. Generation after generation, every male must be circumcised when he is eight days old, including those born in your household and those purchased from a foreigner—even those who are not your offspring. Whether they are born in your household or purchased, they must be circumcised. My covenant in your flesh will be an everlasting covenant.

Significance
Genesis 17 made circumcision "a sign of the covenant" between God and Abraham's household and fixed its day: "every male must be circumcised when he is eight days old" (Genesis 17:11-12). When the eighth day fell on a Sabbath, Israel still circumcised, and Jesus names that exact origin, "not that it is from Moses, but from the patriarchs" (John 7:22). The tie is clear and deliberate, though He argues from the practice rather than quoting the text. His reasoning runs from lesser to greater: if a boy can be circumcised on the Sabbath "so that the law of Moses will not be broken," why the anger "with Me for making the whole man well on the Sabbath?" (John 7:23). The covenant sign touched one part of the body; Jesus made the whole man (ὅλον ἄνθρωπον, G3650 + G444) well, the healing of John 5:8-9. John's own frame carries the claim to Christ: the Son works as the Father works (John 5:17), and Sabbath mercy is His work. The sign given to Abraham's household marked a people as God's; here the Son comes in person to make a man entirely whole, and the Sabbath is shown to be for His restoring mercy.
