At one time when the Buddha was staying at Rājagaha in the Bamboo Grove, the monks Mettiya and Bhūmajaka were descending from the Vulture Peak when they saw two goats copulating. They said to each other, “Let’s give the he-goat the name Dabba the Mallian and the she-goat the name Mettiyā the nun. We can then say, ‘Previously we spoke of what we had heard, but now we’ve seen Dabba copulating with the nun Mettiyā.’” They then gave them those names and told the monks, “Previously we spoke of what we had heard, but now we’ve seen Dabba copulating with the nun Mettiyā.” The monks replied, “Don’t say such things. Venerable Dabba wouldn’t do that.”
