For we have heard how Yahweh dried up the water of the Red Sea before you, when you came out of Egypt; and what you did to the two kings of the Amorites, who were beyond the Jordan, to Sihon and to Og, whom you utterly destroyed.
 We shall find therefore by and by another most important difference, which can be merely touched on passingly now. Here circumcision comes in, expressly contrasted with the previous state of things. Whilst they marched through the wilderness there was no such practice. Not a single person was circumcised that was born in the wilderness: no doubt some were there who had been circumcised before. But when they crossed the Jordan, they must not delay; it was imperative then to be circumcised. Clearly therefore it became a question of death to self by Christ, who is gone on high and united us to Himself there; and this is just the point that is meant by it. Thus the person is free to enter into what God gives above; and there is nothing that hinders this more than self unsubdued and unmortified. Circumcision therefore takes place directly the Jordan is passed. However I am now somewhat anticipating; nevertheless it seemed to me necessary to give these few words of a more general nature in order that there might be a simple and clear impression of the exact difference between the two.
