Rig Veda 9.16

pra te sotāra oṇyo rasam madāya ghṛṣvaye sargo na takty etaśaḥ

The pressers from the Soma-press send forth thy juice for rapturous joy The speckled sap runs like a flood.

kratvā dakṣasya rathyam apo vasānam andhasā goṣām aṇveṣu saścima

With strength we follow through the sieve him who brings might and wins the kine, Enrobed in water with his juice.

anaptam apsu duṣṭaraṃ somam pavitra ā sṛja punīhīndrāya pātave

Pour on the sieve the Soma, ne'er subdued in waters, waterless, And make it pure for Indra's drink.

pra punānasya cetasā somaḥ pavitre arṣati kratvā sadhastham āsadat

Moved by the purifier's thought, the Soma flows into the sieve: By wisdom it hath gained its home.

pra tvā namobhir indava indra somā asṛkṣata mahe bharāya kāriṇaḥ

With humble homage, Indra, have the Soma-drops flowed forth to thee, Contending for the glorious prize.

punāno rūpe avyaye viśvā arṣann abhi śriyaḥ śūro na goṣu tiṣṭhati

Purified in his fleecy garb, attaining every beauty, he Stands, hero-like, amid the kine.

divo na sānu pipyuṣī dhārā sutasya vedhasaḥ vṛthā pavitre arṣati

Swelling, as 'twere, to heights of heaven, the stream of the creative juice Falls lightly on the cleansing sieve.

tvaṃ soma vipaścitaṃ tanā punāna āyuṣu avyo vāraṃ vi dhāvasi

Thus, Soma, purifying him who knoweth song mid living men, Thou wanderest through the cloth of wool.
