Bamidbar 5:19 Meaning and Commentary

Numbers 5:19

And the priest shall charge her by an oath
Or give her her oath:

and say unto the woman, if no man hath lain with thee:
besides her husband:

and thou hast not gone aside to uncleanness [with another] instead of
thy husband;
which is but another phrase expressive of the same thing, the sin of adultery:

be thou free from this bitter water that causeth the curse;
if this is the case, it shall produce no bitter effects, or bring any curse upon thee.
