1.25.2

pitur vacananirdeśāt pitur vacanagauravāt
vacanaṃ kauśikasyeti kartavyam aviśaṅkayā

Thus spoke the saint. Each vigorous word
The noble monarch's offspring heard,
And, reverent hands together laid,
His answer to the hermit made:
'My sire and mother bade me aye
Thy word, O mighty Saint, obey
So will I, O most glorious, kill
This Tádaká who joys in ill,
For such my sire's, and such thy will.
To aid with mine avenging hand
The Bráhmans, kine, and all the land,
Obedient, heart and soul, I stand.'
