RV 10.15.13
ये चेह पितरो ये च नेह यांश् च विद्म यां उ च न प्रविद्म । त्वं वेत्थ यति ते जातवेदः स्वधाभिर् यज्ञं सुकृतं जुषस्व ॥
ye ceha pitaro ye ca neha yāṃś ca vidma yāṃ u ca na pravidma | tvaṃ vettha yati te jātavedaḥ svadhābhir yajñaṃ sukṛtaṃ juṣasva ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Thou, Jatavedas, knowest well the number of Fathers who are here and who are absent, Of Fathers whom we know and whom we know not: accept the sacrifice well prepared with portions.
Translated by Ralph T. H. Griffith (1896)
