Hereunder is given the relevant part of Rig Veda which narrates the story of the ten kings.
Mandala VII
HYMN XVIII. Indra.
5 What though the floods spread widely, Indra made them shallow and easy for Sudas to traverse.
He, worthy of our praises, caused the Simyu, foe of our hymn, to curse the rivers' fury.
6 Eager for spoil was Turvasa Purodas, fain to win wealth, like fishes urged by hunger.
The Bhrgus and the Druhyus quickly listened: friend rescued friend mid the two distant peoples.
7 Together came the Pakthas, the Bhalanas, the Alinas, the Sivas, the Visanins.
Yet to the Trtsus came the Arya's Comrade, through love of spoil and heroes' war, to lead them.
8 Fools, in their folly fain to waste her waters, they parted inexhaustible Parusni.
Lord of the Earth, he with his might repressed them: still lay the herd and the affrighted herdsman.
9 As to their goal they sped to their destruction: they sought Parusni; e'en the swift returned not.
Indra abandoned, to Sudas the manly, the swiftly flying foes, unmanly babblers.
10 They went like kine unherded from the pasture, each clinging to a friend as chance directed.
They who drive spotted steeds, sent down by Prsni, gave ear, the Warriors and the harnessed horses.
11 The King who scattered one-and-twenty people of both Vaikarna tribes through lust of glory-
As the skilled priest clips grass within the chamber, so hath the Hero Indra, wrought their downfall.
12 Thou, thunder-armed, o'erwhelmedst in the waters famed ancient Kavasa and then the Druhyu.
Others here claiming friendship to their friendship, devoted unto thee, in thee were joyful.
13 Indra at once with conquering might demolished all their strong places and their seven castles.
The goods of Anu's son he gave to Trtsu. May we in sacrifice conquer scorned Puru.
14 The Anavas and Druhyus, seeking booty, have slept, the sixty hundred, yea, six thousand,
And six-and-sixty heroes. For the pious were all these mighty exploits done by Indra.
15 These Trtsus under Indra's careful guidance came speeding like loosed waters rushing downward.
The foemen, measuring exceeding closely, abandoned to Sudas all their provisions.
16 The hero's side who drank the dressed oblation, Indra's denier, far o'er earth he scattered.
Indra brought down the fierce destroyer's fury. He gave them various roads, the path's Controller.
17 E'en with the weak he wrought this matchless exploit: e'en with a goat he did to death a lion.
He pared the pillar's angles with a needle. Thus to Sudas Indra gave all provisions.
18 To thee have all thine enemies submitted: e'en the fierce Bheda hast thou made thy subject.
Cast down thy sharpened thunderbolt, O Indra, on him who harms the men who sing thy praises.
19 Yamuna and the Trtsus aided Indra. There he stripped Bheda bare of all his treasures.
The Ajas and the Sigrus and the Yaksus brought in to him as tribute heads of horses.
20 Not to be scorned, but like Dawns past and recent, O Indra, are thy favours and thy riches.
Devaka, Manyamana's son, thou slewest, and smotest Sambara from the lofty mountain.
21 They who, from home, have gladdened thee, thy servants Parasara, Vasistha, Satayatu,
Will not forget thy friendship, liberal Giver. So shall the days dawn prosperous for the princes.
22 Priest-like, with praise, I move around the altar, earning Paijavana's reward, O Agni,
Two hundred cows from Devavan's descendant, two chariots from Sudas with mares to draw them.
23 Gift of Paijavana, four horses bear me in foremost place, trained steeds with pearl to deck them.
Sudas's brown steeds, firmly-stepping, carry me and my son for progeny and glory.
24 Him whose fame spreads between wide earth and heaven, who, as dispenser, gives each chief his portion,
Seven flowing Rivers glorify like Indra. He slew Yudhyamadhi in close encounter.
25 Attend on him O ye heroic Maruts as on Sudas's father Divodasa.
Further Paijavana's desire with favour. Guard faithfully his lasting firm dominion.
HYMN XXXIII Vasistha.
1. THESE who wear hair-knots on the right, the movers of holy thought, white-robed, have won me over.
I warned the men, when from the grass I raised me, Not from afar can my Vasisthas help you.
2 With soma they brought Indra from a distance, Over Vaisanta, from the strong libation.
Indra preferred Vasisthas to the Soma pressed by the son of Vayata, Pasadyumna.
3 So, verily, with these he crossed the river, in company with these he slaughtered Bheda.
So in the fight with the Ten Kings, Vasisthas! did Indra help Sudas through your devotions.
4 I gladly, men I with prayer prayed by our fathers have fixed your axle: ye shall not be injured:
Since, when ye sang aloud the Sakvari verses, Vasisthas! ye invigorated Indra.
5 Like thirsty men they looked to heaven, in battle with the Ten Kings, surrounded and imploring.
Then Indra heard Vasistha as he praised him, and gave the Trtsus ample room and freedom.
6 Like sticks and staves wherewith they drive the cattle, Stripped bare, the Bharatas were found defenceless:
Vasistha then became their chief and leader: then widely. were the Trtsus' clans extended.
7 Three fertilize the worlds with genial moisture: three noble Creatures cast a light before them.
Three that give warmth to all attend the morning. All these have they discovered, these Vasisthas.
8 Like the Sun's growing glory is their splendour, and like the sea's is their unflathomed greatness.
Their course is like the wind's. Your laud, Vasisthas, can never be attained by any other.
9 They with perceptions of the heart in secret resort to that which spreads a thousand branches.
The Apsaras brought hither the Vasisthas wearing the vesture spun for them by Yama.
10 A form of lustre springing from the lightning wast thou, when Varuna and Mitra saw thee.
Tliy one and only birth was then, Vasistha, when from thy stock Agastya brought thee hither.
11 Born of their love for Urvasi, Vasistha thou, priest, art son of Varuna and Mitra;
And as a fallen drop, in heavenly fervour, all the Gods laid thee on a lotus-blossorn.
12 He thinker, knower both of earth and heaven, endowed with many a gift, bestowing thousands,
Destined to wear the vesture spun by Yama, sprang from the Apsaras to life, Vasistha.
13 Born at the sacrifice, urged by adorations, both with a common flow bedewed the pitcher.
Then from the midst thereof there rose up Mana, and thence they say was born the sage Vasistha.
14 He brings the bearer of the laud and Saman: first shall he speak bringing the stone for pressing.
With grateful hearts in reverence approach him: to you, O Pratrdas, Vasistha cometh.
HYMN LXXXIII. Indra-Varuna.
Hymn LXXXIII
4 With your resistless weapons, Indra-Varuna, ye conquered Bheda and ye gave Sudas your aid.
Ye heard the prayers of these amid the cries of war: effectual was the service of the Trtsus' priest.
5 O Indra-Varuna, the wickedness of foes and mine assailants' hatred sorely trouble me.
Ye Twain are Lords of riches both of earth and heaven: so grant to us your aid on the decisive day.
6 The men of both the hosts invoked you in the fight, Indra and Varuna, that they might win the wealth,
What time ye helped Sudas, with all the Trtsu folk, when the Ten Kings had pressed him down in their attack.
7 Ten Kings who worshipped not, O Indra-Varuna, confederate, in war prevailed not o'er Sudas.
True was the boast of heroes sitting at the feast: so at their invocations Gods were on their side.
8 O Indra-Varuna, ye gave Sudas your aid when the Ten Kings in battle compassed him about,
There where the white-robed Trtsus with their braided hair, skilled in song worshipped you with homage and with hymn.
