RV 10.122.4
यज्ञस्य केतुम् प्रथमम् पुरोहितं हविष्मन्त ईळते सप्त वाजिनम् । शृण्वन्तम् अग्निं घृतपृष्ठम् उक्षणम् पृणन्तं देवम् पृणते सुवीर्यम् ॥
yajñasya ketum prathamam purohitaṃ haviṣmanta īḷate sapta vājinam | śṛṇvantam agniṃ ghṛtapṛṣṭham ukṣaṇam pṛṇantaṃ devam pṛṇate suvīryam ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The seven who bring oblations worship thee, the Strong, the first, the Great Chief Priest, Ensign of sacrifice, The oil-anointed Bull, Agni who hears, who sends as God full hero strength to him who freely gives.
Translated by Ralph T. H. Griffith (1896)
