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 shall set the woman before Jehovah, and let the hair of the woman's head go loose, and put the meal-offering of memorial in her hands, which is the meal-offering of jealousy: and the priest shall have in his hand the water of bitterness that causeth the curse.
19 And the priest shall cause her to swear, and shall say unto the woman, If no man have lain with thee, and if thou have not gone aside to uncleanness, being under thy husband, be thou free from this water of bitterness that causeth the curse.
20 But if thou have gone aside, being under thy husband, and if thou be defiled, and some man have lain with thee besides thy husband:
21 then the priest shall cause the woman to swear with the oath of cursing, and the priest shall say unto the woman, Jehovah make thee a curse and an oath among thy people, when Jehovah doth make thy thigh to fall away, and thy body to swell;
22 and this water that causeth the curse shall go into thy bowels, and make thy body to swell, and thy thigh to fall away. And the woman shall say, Amen, Amen.
