Ecclesiastes 7:27-29 Amplified Bible (AMP)

27. Behold, this I have found, says the Preacher, while weighing one thing after another to find out the right estimate [and the reason]–

28. Which I am still seeking but have not found–one upright man among a thousand have I found, but an upright woman among all those [one thousand in my harem] have I not found. [I Kings 11:3.]

29. Behold, this is the only [reason for it that] I have found: God made man upright, but they [men and women] have sought out many devices [for evil].
