The Rāmāyaṇa of Vālmīki 2.31.25

2.31.25

bhavān varṣasahasrāya pṛthivyā nṛpate patiḥ
ahaṃ tv araṇye vatsyāmi na me kāryaṃ tvayānṛtam

Thus by the lord of men addressed,
Ráma, of virtue's friends the best,
In lore of language duly learned,
His answer, reverent, thus returned:
'A thousand years, O King, remain
O'er this our city still to reign.
I in the woods my life will lead:
The lust of rule no more I heed.
Nine years and five I there will spend,
And when the portioned days shall end,
Will come, my vows and exile o'er,
And clasp thy feet, my King, once more.'
