RV 1.51.8
वि जानीह्य् आर्यान् ये च दस्यवो बर्हिष्मते रन्धया शासद् अव्रतान् । शाकी भव यजमानस्य चोदिता विश्वेत् ता ते सधमादेषु चाकन ॥
vi jānīhy āryān ye ca dasyavo barhiṣmate randhayā śāsad avratān | śākī bhava yajamānasya coditā viśvet tā te sadhamādeṣu cākana ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Discern thou well Aryas and Dasyus; punishing the lawless give them up to him whose grass is strewn. Be thou the sacrificer's strong encourager all these thy deeds are my delight at festivals.
Translated by Ralph T. H. Griffith (1896)
