'Seek' in the Bible

And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

A time to seek, and a time to lose; A time to keep, and a time to cast away;

I turned, I and my heart, to know, and to search, and to seek out wisdom and reason, and to know wickedness to be folly, and foolishness to be madness;

then I saw that all is the work of God, and that man cannot find out the work that is done under the sun: because however man may labour to seek it out, yet doth he not find it; and even, if a wise man think to know it, he shall not be able to find it out.
