These uncircumcised; so he calls them, partly in contempt, and principally to strengthen his faith by this consideration, that his enemies were enemies to God, and without any hope in God, or help from him; whereas he was circumcised, and therefore in covenant with God, who was both able and engaged to assist his people. It may be; he speaks doubtfully; for though he found and felt himself stirred up by God to this exploit, and was assured that God would deliver his people, yet he was not certain that he would do it at this time, and in this way. The Lord will work, to wit, great and wonderful things. There is no restraint to the Lord; there is no person nor thing which can hinder God from thus doing.
