Mbh 1.104.6a

“Hearing these words of his wife, the Rishi became indignant and said unto her and her children, ‘Take me unto the Kshatriyas and thou shalt then be rich.’ His wife replied (by saying), ‘I desire not wealth that may be procured by thee, for that can never bring me happiness. O best of Brahmanas, do as thou likest. I shall not be able to maintain thee as before.’ At these words of his wife, Dirghatamas said, ‘I lay down from this day as a rule that every woman shall have to adhere to one husband for her life. Be the husband dead or alive, it shall not be lawful for a woman to have connection with another. And she who may have such connection shall certainly be regarded as fallen. A woman without husband shall always be liable to be sinful. And even if she be wealthy she shall not be able to enjoy that wealth truly. Calumny and evil report shall ever dog her.’ Hearing these words of her husband Pradweshi became very angry, and commanded her sons, saying, ‘Throw him into the waters of Ganga!’ And at the command of their mother, the wicked Gautama and his brothers, those slaves of covetousness and folly, exclaiming, ‘Indeed, why should we support this old man?--‘tied the Muni to a raft and committing him to the mercy of the stream returned home without compunction. The blind old man drifting along the stream on that raft, passed through the territories of many kings. One day a king named Vali conversant with every duty went to the Ganges to perform his ablutions. And as the monarch was thus engaged, the raft to which the Rishi was tied, approached him. And as it came, the king took the old man. The virtuous Vali, ever devoted to truth, then learning who the man was that was thus saved by him, chose him for raising up offspring. And Vali said, ‘O illustrious one, it behoveth thee to raise upon my wife a few sons that shall be virtuous and wise.’ Thus addressed, the Rishi endued with great energy, expressed his willingness.
