6.62.1

vaiśvānaró raśmíbhir naḥ punātu vā́taḥ prāṇéneṣiró nábhobhiḥ |
dyā́vāpr̥thivī́ páyasā páyasvatī r̥tā́varī yajñiye na punītām ||1||

Let Vāiçvānara (Agni) by his rays purify us, the wind, lively with mists (? nábhas), by his breath; let heaven-and-earth, rich in milk, righteous, worshipful, purify us by milk.
