I gave
Ecclesiastes 1:13
And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.
Ecclesiastes 2:3
I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what was that good for the sons of men, which they should do under the heaven all the days of their life.
Ecclesiastes 2:12
And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been already done.
Ecclesiastes 7:23-25
23
All this have I proved by wisdom: I said, I will be wise; but it was far from me.
24
That which is far off, and exceeding deep, who can find it out?
25
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:
1 Thessalonians 5:21
Prove all things; hold fast that which is good.
I perceived
Ecclesiastes 2:10
And whatsoever mine eyes desired I kept not from them, I withheld not my heart from any joy; for my heart rejoiced in all my labour: and this was my portion of all my labour.
Ecclesiastes 2:11
Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
