How is that a valid source?
But it does support the claim that if she was pregnant she would lose the fetus:
"Thy belly to swell, and thy thigh to rot - What is meant by these expressions cannot be easily ascertained. ירך לנפל lanpel yarech signifies literally thy thigh to fall. As the thigh, feet, etc., were used among the Hebrews delicately to express the parts which nature conceals, (see
Genesis 46:26, the expression here is probably to be understood in this sense; and the falling down of the thigh here must mean something similar to the
prolapsus uteri, or falling down of the womb, which might be a natural effect of the preternatural distension of the abdomen. In
1 Corinthians 11:29, St. Paul seems to allude to the case of the guilty woman drinking the bitter cursed waters that caused her destruction: He who eateth and drinketh unworthily, eateth and drinketh damnation (κριμα, condemnation or judgment) to himself; and there is probably a reference to the same thing in
Psalm 109:18, and in
Daniel 9:11."
If she was pregnant a prolapsed uterus would definitely do the job.
