RV 1.164.16
स्त्रियः सतीस् तां उ मे पुंस आहुः पश्यद् अक्षण्वान् न वि चेतद् अन्धः । कविर् यः पुत्रः स ईम् आ चिकेत यस् ता विजानात् स पितुष् पितासत् ॥
striyaḥ satīs tāṃ u me puṃsa āhuḥ paśyad akṣaṇvān na vi cetad andhaḥ | kavir yaḥ putraḥ sa īm ā ciketa yas tā vijānāt sa pituṣ pitāsat ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
They told me these were males, though truly females: he who hath eyes sees this, the blind discerns not. The son who is a sage hath comprehended: who knows this rightly is his father's father.
Translated by Ralph T. H. Griffith (1896)
