Reṇukā was the foster daughter of the king Prasenajit. He had found her as a baby-girl lying on a lotus flower. She was married to the sage Jamadagni. She bore him five sons of whom Paraśurāma was the youngest.
Once, suspecting her fidelity, Jamadagni asked his sons one by one, to behead her. None obeyed him except Paraśurāma, who promptly beheaded not only Reṇukā but also the elder brothers, as per the command of his father. Pleased with his implicit obedience, Jamadagni asked him to choose any boon. Paraśurāma earnestly requested him to bring them all back to life.
