Atharvaveda 3.30

Like-heartedness, like-mindedness, non-hostility do I make for you; do ye show affection (hary) the one toward the other, as the inviolable [cow] toward her calf when born.

Be the son submissive to the father, like-minded with the mother; let the wife to the husband speak words (vā́c) full of honey, wealful.

Let not brother hate brother, nor sister sister; becoming accordant (samyáñc), of like courses, speak ye words auspiciously (bhadráyā).

That incantation in virtue of which the gods do not go apart, nor hate one another mutually, we perform in your house, concord for [your] men (púruṣa).

Having superiors (jyā́yasvant), intentful, be ye not divided, accomplishing together, moving on with joint labor (sádhura); come hither speaking what is agreeable one to another; I make you united (sadhrīcī́na), like-minded.

Your drinking (prapā́) [be] the same, in common your share of food; in the same harness (yóktra) do I join ⌊yuj⌋ you together; worship ye Agni united, like spokes about a nave.

United, like-minded I make you, of one bunch, all of you, by [my] conciliation; [be] like the gods defending immortality (amṛ́ta); late and early be well-willing yours.
