5.3.26

ayaṃ vai tvamasmādayaṃ te yonistvamasya yoniḥ \ pitā putrasya lokakujjātavedaḥ \ vahasvainaṃ sukṛtām̐ yatra lokaḥ \ ayaṃ vai tvāmajanayadayaṃ tvayi jāyatāmasau svāhā iti sruveṇa hutvodaṅṅutkrāmanti \26\

Having offered with the sruva: 'This indeed are you from this one; this is your womb, you are his womb. / Father, preparing a world for the son, O Jātavedas, / bear him to where the world of the righteous is. / This one indeed begot you; may he be born in you, so-and-so, svāhā!', they step out toward the north.
