ChU 2.8.3
दुग्धे ऽस्मै वाग् दोहं यो वाचो दोहः । अन्नवान् अन्नादो भवति । य एतद् एवं विद्वान् वाचि सप्तविधं सामोपास्ते
dugdhe 'smai vāg dohaṃ yo vāco dohaḥ | annavān annādo bhavati | ya etad evaṃ vidvān vāci saptavidhaṃ sāmopāste
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Speech yields the milk, which is the milk of speech itself, to him who knowing this meditates on the sevenfold Sâman in speech. He becomes rich in food, and able to eat food.
Translated by F. Max Müller
