Ja 120 The Story about Freedom from Bondage
(Bandhanamokkhajātaka)

In the present Ciñcā falsely accuses the Buddha of fathering a child on her. After Sakka reveals the falsehood, she falls into hell. The Buddha tells a story about a queen who cheated with 64 men and then falsely accused the king’s family priest of adultery, until it was discovered (full story).

1. Abaddhā tattha bajjhanti, yattha bālā pabhāsare,
Baddhā pi tattha muccanti, yattha dhīrā pabhāsare ti.

They bind the unbound right there, where fools speak, they free the bound right there, where the wise speak.

In this connection, unbound means those fit to be unbound.

Speak means they speak, talk, tell.
