3.10.4

iyám evá sā́ yā́ prathamā́ vyáuchad āsv ítarāsu carati práviṣṭā |
mahā́nto asyāṃ mahimā́no antár vadhū́r jigāya navagáj jánitrī ||4||

This same is she that first shone out; among these other ones (f.) she goes about (car), having entered; great greatnesses [are] within her; the bride (vadhū́), the new-going generatrix, hath conquered.
