And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin.

And Abraham is a son of ninety and nine years in the flesh of his foreskin being circumcised;

Abraham was ninety-nine years old when he underwent circumcision.

Abraham autem erat vir nonaginta et novem annorum, quando circumcisa fuit carno praeputii ipsius.

And Abraham was ninety years old and nine,.... See Genesis 17:1. This circumstance of his age is observed the more to commend his faith and obedience, that though he was an old man, he did not consider his age, or make that an objection; that he was unable to bear the pain, or it would be shameful for a man of his years to be uncovered before his servants:
when he was circumcised in the flesh of his foreskin; who circumcised him is not said, very probably Eliezer his head servant: the Jews, who affect to know everything, say (u), that he sent for Shem, the son of Noah, who circumcised him and his son Ishmael; but it is most likely that Ishmael was circumcised by Abraham himself, as seems from Genesis 17:23; and Abraham might circumcise himself, as Ben Melech thinks.
(u) Pirke Eliezer, c. 29.
