Targum Jonathan on Numbers
and may these waters of trial enter into thy bowels, to cause thy belly to swell, and thy thigh to corrupt. And the woman shall answer and say: Amen, if I was polluted when betrothed; Amen, if I have been polluted since my marriage.
Targum Jerusalem
And the woman shall answer, Amen, because I have not been unclean; Amen, if ever I shall have wrought uncleanness.
