RV 10.87.21
पश्चात् पुरस्ताद् अधराद् उदक्तात् कविः काव्येन परि पाहि राजन् । सखे सखायम् अजरो जरिम्णे ऽग्ने मर्तां अमर्त्यस् त्वं नः ॥
paścāt purastād adharād udaktāt kaviḥ kāvyena pari pāhi rājan | sakhe sakhāyam ajaro jarimṇe 'gne martāṃ amartyas tvaṃ naḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
From rear, from front, from under, from above us, O King, protect us as a Sage with wisdom. Guard to old age thy friend, O Friend, Eternal: O Agni, as Immortal, guard us mortals.
Translated by Ralph T. H. Griffith (1896)
