Vishnupurana 4.7.20

When Richíka returned home, and beheld Satyavatí, he said to her, "Sinful woman, what hast thou done! I view thy body of a fearful appearance. Of a surety thou hast eaten the consecrated food which was prepared for thy mother: thou hast done wrong. In that food I had infused the properties of power and strength and heroism; in thine, the qualities suited to a Brahman, gentleness, knowledge, and resignation. In consequence of having reversed my plans, thy son shall follow a warrior's propensities, and use weapons, and fight, and slay. Thy mother's son shall be born with the inclinations of a Brahman, and be addicted to peace and piety." Satyavatí, hearing this, fell at her husband's feet, and said, "My lord, I have done this thing through ignorance; have compassion on me; let me not have a son such as thou hast foretold: if such there must be, let it be my grandson, not my son." The Muni, relenting at her distress, replied, "So let it be." Accordingly in due season she gave birth to Jamadagni; and her mother brought forth Viswamitra. Satyavatí afterwards became the Kauśikí river. Jamadagni married Reńuká, the daughter of Reńú, of the family of Ikshwáku, and had by her the destroyer of the Kshatriya race, Paraśuráma, who was a portion of Náráyańa, the spiritual guide of the universe.
