John Chrysostom, on Gen 17:24

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

“Don't think it was without purpose that Scripture indicated to us his age; instead, it was for you to learn from the just man's obedience in meekly submitting to pain despite his extreme old age on account of God's command, and not only he but also Ishmael and all the servants—that was the reason for giving the ages.”
