Medhātithi’s commentary (manubhāṣya):
The present verse is added with a view to indicate the man’s title to another marriage; i.e., an exception in favour of his wedding another wife; and it also serves to prohibit the man forthwith taking to the life of the Recluse or the Renunciate, as soon as he finds himself deprived of his help-mate and this because he has still got to fulfil certain duties. Says the Śruti—‘He is abandoned by old age, or by the omission of his duties.’

Others say that a ‘yadā’, ‘when’, should be supplied in this verse; so that there would be no incompatibility between this end the Śruti laying down life-long Āgnihotra.—(166).
