Числа 5:21

Spiritual Organization of theCongregation of Israel - Numbers 5-6 From the outward organization of the tribes of Israel as the army of Jehovah, the law proceeds to their internal moral and spiritual order, for the purpose of giving an _inward support, both moral and religious, to their outward or social and political unity. This is the object of the directions concerning the removal of unclean persons from the camp (Num 5:1-4), the restitution of anything unjustly appropriated (Num 5:5-10), the course to be pursued with a wife suspected of adultery (Num 5:11-31), and also of the laws relating to the Nazarite (Num 6:1-21), and to the priestly blessing (Num 6:22-27).

In this chapter we have, I. An order, pursuant to the laws already made, for the removing of the unclean out of the camp (Num 5:1-4). II. A repetition of the laws concerning restitution, in case of wrong done to a neighbour (Num 5:5-8), and concerning the appropriating of the hallowed things to the priests (Num 5:9, Num 5:10). III. A new law made concerning the trial of a wife suspected of adultery, by the waters of jealousy (Num 5:11, etc.).

Gen 24:2; 47:29); something would go wrong with her reproductive abilities. The punishment suited the crime as sexual immorality resulted in the inability to have children.
