Before any male could eat the Passover he had to undergo circumcision. Moses stressed this stipulation strongly in this section. The rationale behind this rule was that before anyone could observe the memorial of redemption he first had to exercise faith in the promises God had given to Abraham. Furthermore he had to demonstrate that faith by submitting to the rite of circumcision, the sign of the Abrahamic Covenant. This requirement should have reminded the Israelites and all other believers who partook of the Passover that the Passover rite did not make a person acceptable to God. Faith in the promises of God did that. Foreigners who were non-Israelites could and did become members of the nation by faith in the Abrahamic Covenant promises and participation in the rite of circumcision. There were both circumcised and uncircumcised foreigners who lived among the Israelites during the wilderness march.
Here Moses revealed the requirement that the Passover host was not to break a bone of the paschal lamb (v. 46; cf. vv. 3-9). Not a bone of the Lamb of God was broken either (John 19:36).
