'Though' in the Bible

There is a person without a companion, without even a son or brother, and though there is no end to all his struggles, his eyes are still not content with riches. “So who am I struggling for,” he asks, “and depriving myself from good?” This too is futile and a miserable task.

For he came from prison to be king, even though he was born poor in his kingdom.

Though a stillborn child does not see the sun and is not conscious, it has more rest than he.

For every activity there is a right time and procedure, even though man’s troubles are heavy on him.

When I applied my mind to know wisdom and to observe the activity that is done on the earth (even though one’s eyes do not close in sleep day or night),

I observed all the work of God and concluded that man is unable to discover the work that is done under the sun. Even though a man labors hard to explore it, he cannot find it; even if the wise man claims to know it, he is unable to discover it.
