'Though' in the Bible

And went to sleep and got up, night and day, and the seed came to growth, though he had no idea how.

Who will not get a hundred times as much now in this time, houses, and brothers, and sisters, and mothers, and children, and land--though with great troubles; and, in the world to come, eternal life.

But Peter said to him, Though the others may be turned away from you, I will not.
