'Harmless' in the Bible

then the priest shall look, and if the bright spots on the skin of their bodies is a dull white, it is [only] a rash that has broken out on the skin; he is clean.

But David said, “What have I done now? Was it not just a [harmless] question?”

“Listen carefully: I am sending you out like sheep among wolves; so be wise as serpents, and innocent as doves [have no self-serving agenda].
