2.48.10

upadruteṣveṣu parāṅmukho yaḥ syustasya devāḥ sakalāḥ parāṅmukhāḥ /
tilodakaṃ naiva pibanti pūrve hutaṃ na gṛhṇāti hutāśanopi tat //

whoever turns his back when these are assailed, all the gods turn their backs on him. / The ancestors do not drink his water with sesame seeds, nor does the fire receive what is offered [by him].
