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.
