sārvavarṇikam annādyaṃ saṃnīyāplāvya vāriṇā
samutsṛjed bhuktavatām agrato vikiran bhuvi //

The leavings (that have remained in the dishes) and what has been strewn (in the manner just mentioned) upon the blades of Kusa grass (spread on the ground) is the share of such (Brâhmanas) as have died before they were initiated, and of husbands who have deserted wives descended from good families.
