vyabhicaram munir jñatva
patnyah prakupito ’bravit
ghnatainam putrakah papam
ity uktas te na cakrire
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great sage Jamadagni understood the adultery in the mind of his wife. Therefore he was very angry and told his sons, “My dear sons, kill this sinful woman!” But the sons did not carry out his order.
