2.34.1

yá ī́śe paśupátiḥ paśūnā́m cátuṣpadām utá yó dvipádām |
níṣkrītaḥ sá yajñíyaṃ bhāgám etu rāyás póṣā yájamānaṃ sacantām ||1||

The lord of cattle, who rules over (īç) the cattle, the four-footed, and who also over the two-footed—let him, bought off, go to [his] sacrificial portion; let abundances of wealth attach themselves to (sac) the sacrificer.
