Atharva Veda 6.140: A blessing on a child's first two teeth

Two tigers have grown up who long to eat the mother and the sire: Soothe, Brāhmanaspati, and thou, O Jātavedas, both these teeth.

Let rice and barley be your food, eat also beans and sesamum.
This is the share allotted you, to be your portion, ye two Teeth.
Harm not your mother and your sire.

Both fellow teeth have been invoked, gentle and bringing happi-ness.
Else whither let the fierceness of your nature turn away, O Teeth! Harm not your mother or your sire.
