The Rāmāyaṇa of Vālmīki 3.28.8

3.28.8

avaśyaṃ labhate kartā phalaṃ pāpasya karmaṇaḥ
ghoraṃ paryāgate kāle drumaḥ puṣpam ivārtavam

Thy hand has slain the pure and good,
The hermit saints of Dandak wood,
Of holy life, the heirs of bliss;
And thou shalt reap the fruit of this.
Not long shall they whose cruel breasts
Joy in the sin the world detests
Retain their guilty power and pride,
But fade like trees whose roots are dried.
Yes, as the seasons come and go.
Each tree its kindly fruit must show,
And sinners reap in fitting time
The harvest of each earlier crime.
As those must surely die who eat
Unwittingly of poisoned meat,
They too whose lives in sin are spent
Receive ere long the punishment.
And know, thou rover of the night,
That I, a king, am sent to smite
The wicked down, who court the hate
Of men whose laws they violate.
This day my vengeful hand shall send
Shafts bright with gold to tear and rend,
And pass with fury through thy breast
As serpents pierce an emmet's nest.
Thou with thy host this day shalt be
Among the dead below, and see
The saints beneath thy hand who bled,
Whose flesh thy cruel maw has fed.
They, glorious on their seats of gold,
Their slayer shall in hell behold.
Fight with all strength thou callest thine,
Mean scion of ignoble line,
Still, like the palm-tree's fruit, this day
My shafts thy head in dust shall lay.'
