'Though' in the Bible

Because out of a prison the young man comes to be king, though by birth he was only a poor man in the kingdom.

And though he goes on living a thousand years twice over and does not see good, are not the two going to the same place?

Though a sinner does evil a hundred times and his life is long, I am certain that it will be well for those who go in fear of God and are in fear before him.
