John Wesley on Joshua 5:2

At that time - As soon as ever they were come to Gilgal, which was on the tenth day; and so this might be executed the eleventh day, and that in the morning: on the thirteenth day they were sore of their wounds, and on the fourteenth day they recovered, and at the even of that day kept the passover. Make - Or, prepare, or make ready, as this word sometimes used. As it was not necessary for those who had such knives already to make others for that use; so it is not probable that such were commanded to do so, but only to make them sharp and fit for that work. The second time - He calleth this a second circumcision, not as if these same persons had been circumcised before, but with respect to the body of the people, where of one part had been circumcised before, and the other at this time, which is called a second time, in relation to some former time wherein they were circumcised, either, in Egypt, when many of the people, who possibly for fear or favour of the Egyptians, had neglected this duty, were by the command of Moses circumcised. Or at Sinai, when they received the passover, Numb 9:5, which no uncircumcised person might do.
