Numbers 5:20

20 and thou, if thou hast turned aside under thy husband, and if thou hast been defiled, and any man doth give his copulation to thee besides thy husband --

Numbers 5:20 Meaning and Commentary

Numbers 5:20

But if thou hast gone aside to another instead of thy
husband
Gone aside from the paths of modesty and chastity, and betook herself to another man's bed instead of her husband's:

and if thou be defiled,
by committing adultery:

and some man hath lain with thee beside thy husband;
these phrases are all synonymous, and a heap of words are made use of to express the sin, and that there might be no evasion of it, and that it might be clear what was intended, this being said on oath.

Numbers 5:20 In-Context

18 and the priest hath caused the woman to stand before Jehovah, and hath uncovered the woman's head, and hath given into her hands the present of the memorial, it [is] a present of jealousy, and in the hand of the priest are the bitter waters which cause the curse.
19 `And the priest hath caused her to swear, and hath said unto the woman, If no man hath lain with thee, and if thou hast not turned aside [to] uncleanness under thy husband, be free from these bitter waters which cause the curse;
20 and thou, if thou hast turned aside under thy husband, and if thou hast been defiled, and any man doth give his copulation to thee besides thy husband --
21 (then the priest hath caused the woman to swear with an oath of execration, and the priest hath said to the woman) -- Jehovah doth give thee for an execration, and for a curse, in the midst of thy people, in Jehovah's giving thy thigh to fall, and thy belly to swell,
22 and these waters which cause the curse have gone into thy bowels, to cause the belly to swell, and the thigh to fall; and the woman hath said, Amen, Amen.
