[And he circumcised the children of Israel] That is, he took care that they be circumcised (Vatablus). And it is likely that on the same day (with Joshua seeing to this, and with the Levites left among them) the Jews on the other side of Jordan were circumcised (Bonfrerius). It belongs to a good Prince to revive intermitted rites. See 2 Kings 23 (Grotius).
Joshua…circumcised, etc.: that is, He caused this to be done; and because it was to be done speedily, the passover approaching, it was necessary to use many hands in it, either priests and Levites, or other circumcised persons, who, at least in those circumstances, were permitted to do it. The children of Israel, that is, such of them as were uncircumcised. And though it be not mentioned, it is more than probable, that the Israelites beyond Jordan were circumcised at the same time.
[On the hill of foreskins (thus the Syriac, Drusius), אֶל/to in the place of ב/on (Drusius), אֶל־גִּבְעַ֖ת הָעֲרָלֽוֹת׃] At (or near [Arabic]) the hill of foreskins (Montanus, Junius and Tremellius), or, of the uncircumcised (Septuagint, Syriac, Arabic). The place was so called by anticipation (Masius), because there their foreskins were left or cast aside (Masius, Junius, Drusius, Vatablus): or, because the foreskins of the Jews piled together into a heap made a hill (Drusius, Hebrews in Masius).
