ליטעראַטור פֿון בית שני אויף במדבר 5:28

[150] This explains “the breaking up of the thigh,” being added as the sequel to the swelling of the belly. For then it is that the soul experiences the breaking up of the right principle, the principle that is the seed whence all noble things are begotten. We see this from the words that follow, “If she have not been defiled and be pure, she shall be free and shall conceive seed” (Numb. 5:28), if she have not been defiled by passion, but have been chaste and faithful to her lawful husband, the princely and wholesome principle, she will have a soul fruitful and productive, yielding the offspring of sound sense and righteousness and all excellence.
