Romans 4:10

How was it then reckoned? - In what circumstances was Abraham when this blessing was bestowed upon him? When he was circumcised, or before?

Not in circumcision, but in uncircumcision - Faith was reckoned to Abraham for justification, as we read Genesis 15:6 , (see the note on Genesis 15:6 ;); but circumcision was not instituted till about fourteen or fifteen years after, Genesis 17:1 , etc.; for faith was reckoned to Abraham for righteousness or justification at least one year before Ishmael was born; compare Genesis 15, and 16. At Ishmael's birth he was eighty-six years of age, Genesis 16:16 ; and, at the institution of circumcision, Ishmael was thirteen, and Abraham ninety-nine years old. See Genesis 17:24 , Genesis 17:25 ; and see Dr. Taylor.
