John Gill, on Gen 17:27

“And all the men of his house, as well they that were born in his house, as the bought servants and strangers were circumcised with him.”

“And all the men of his house,.... All the males, whether children or adult: born in the house, or bought with money of the stranger, were circumcised with him; by their will, and with their consent; not forced to it, as Aben Ezra rightly observes; and these being before trained up by him in religious exercises, were more easily prevailed upon by him to follow his example; this also is repeated, that it might be served, and be an example to follow in after generations. Next: Genesis Chapter 18”
