1.4.2.49

śaktiviṣaye ca ślokā bhavaṃti..
kuṭuṃbabhuktavasanāddeyaṃ yadatiricyate..
madhvāsvādo viṣaṃ paścāddāturdharmo'nyathā bhavet.. 4.49 ..

And on the subject of capacity, there are these verses:
What remains beyond the food and clothing of one's family is to be given;
otherwise, a giver's righteousness becomes sweet at first like honey, but poison in the end.
