'Though' in the Bible

Yes, though he live a thousand years twice told, and yet fails to enjoy good, don't all go to one place?

Though a sinner commits crimes a hundred times, and lives long, yet surely I know that it will be better with those who fear God, who are reverent before him.

then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.
