Atharvaveda 20.25

Indra, the mortal man well guarded by thine aid goes foremost in the wealth of horses and of kine.
With amplest wealth thou fillest him, as round about the waters clearly seen afar fill Sindhu full.

The heavenly waters come not nigh the priestly bowl: they but look down and see how far mid-air is spread:
The Deities conduct the pious man to them: like suitors they delight in him who loveth prayer.

Praiseworthy blessing hast thou laid upon the pair who with uplifted ladle serve thee, man and wife.
Unchecked he dwells and prospers in thy law: thy power brings blessing to the sacrificer pouring gifts.

First the Angirases won themselves vital power, whose fires were kindled through good deeds and sacrifice.
The men together found the Pani's hoarded wealth, the cattle, and the wealth in horses and in kine,

Atharvan first by sacrifices laid the path; then, guardian of the
Law, sprang up the loving Sun.
Usanā Kāvya drove the kine hither with him: let us with offer- ings honour Yama's deathless birth.

When sacred grass is trimmed to aid the auspicious work, or the hymn makes its voice of praise sound to the sky,
Where the stone rings as 'twere a singer skilled in laud,—Indra in truth delights when these come near to him.

To make thee start, a strong true draught I offer to thee the
Bull, O thou whom bay steeds carry.
Here take delight. O Indra, in our voices while thou art hymned with power and all our spirit.
