Joshua 5:4-7

Ver. 4-7. And this is the cause, &c.— The reason is clearly expressed in the text. Excepting Joshua and Caleb, all the six hundred thousand fighting men, who came out of Egypt, had died during the forty years that the people had dwelt in the desarts of Arabia; and during this interval of time they had neglected to circumcise the male children which were born there. But whence this negligence? It was not out of contempt, since the Scripture nowhere reproaches the Israelites on that account. But the learned have given us the following reasons for this long interruption of circumcision.

I. That the end of the ceremonial laws, especially circumcision, being to distinguish the Jews from the idolatrous nations, it was unnecessary to circumcise them in the desart, where it was not possible for them to mix with other people. This was the opinion of Theodoret and St. Jerome among the ancients; as it was of Grotius, Episcopius, and Le Clerc, among the moderns: we find it also espoused by Mr. Pyle.
II. The second and most generally received reason is, that the almost incessant motions of the Israelites, the uncertainty of the times of decamping, the barrenness of the places where they sojourned, and the inconveniences of travelling, rendering the operation very dangerous for children, God willingly dispensed with it. Some judicious rabbis have adopted this opinion; and it has been countenanced by several able commentators among us.
III. But these reasons do not seem equally satisfactory to every body. The marches of the Israelites were very far from being frequent during the last thirty-eight years of their stay in the wilderness. Besides, it would have been better to make some alteration with respect to time, and to refer this ceremony to the first encampment, instead of fixing it to the eighth day, rather than to omit it entirely; seeing that certain blessings were annexed to it. So that, in this respect, the practice of circumcision was indispensable, though the primary end of the institution was to prevent the children of Israel from forming connections with foreign nations. Add to this, that the latter consideration could not excuse them from the observation of a positive precept, even though circumcision had not been in use among any of the nations; which was by no means the case, this ceremony being practised by the Idumeans, and perhaps even by the Midianites. These, and other reflections, have determined some judicious critics to say, that circumcision was interrupted during the time that the Israelites travelled in the desart, because they did not esteem the precept of circumcision obligatory, till they saw themselves settled in the land of Canaan; and so much the rather, as there was nothing in this respect prescribed on the renewing of the covenant which was made at the foot of mount Sinai. Hence we may conclude, that circumcision was not so necessary to salvation as some writers, as well Christians as Jews, have thought; particularly the latter, among whom some have carried their superstition so far, as to circumcise their children even dead, when they could not do it while they lived.
Lastly, a writer of great reputation has advanced a conjecture, that the mixed multitude of the Egyptians which followed the Israelites being an image of the calling, of the Gentiles, it became necessary, that as the ceremonies, and particularly circumcision, were to be abolished; so, to take away the distinction which was between their posterity, the use of circumcision should be then suspended. Besides, God was unwilling that the suspension of this ceremony should continue till the Israelites took possession of the land of Canaan: 1st, For fear it might give room for the intrusion of Canaanites among the Hebrews. 2nd, That those who entered into the land of Canaan, being uncircumcised, as well as the children of the Egyptians, and afterwards becoming equal by circumcision, might have no opportunity to reproach them for their different original. See Allix on the Pentateuch.

Whatever may be the truth, or the different degrees of probability or strength of these reflections; it is certain, that God did not condemn the interruption of circumcision, or impute any crime to the Israelites on that account: and we may easily conceive, that the precept not being founded in nature, but merely positive and ceremonial, the argument drawn from the inconveniences of travelling was alone sufficient for dispensing with it under the divine approbation. The Israelites then only followed a maxim which they have generally followed; namely, that the administration of this sacrament may be deferred when it cannot be received without danger.
