'Reason' in the Bible

Though the stillborn child came into the world for no reason and departed into darkness, though its name is shrouded in darkness,

I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:

See, this I have found, said the Preacher, one to one, to find out the reason

Behold, I have found only this [as a reason]: God made man upright and uncorrupted, but they [both men and women] have sought out many devices [for evil].”

Dead flies cause a perfumer's perfume To send forth a stink; The precious by reason of wisdom -- By reason of honour -- a little folly!
