'Though' in the Bible

Brothers and sisters, I offer an example from everyday life: When a covenant has been ratified, even though it is only a human contract, no one can set it aside or add anything to it.

Now I mean that the heir, as long as he is a minor, is no different from a slave, though he is the owner of everything.

and though my physical condition put you to the test, you did not despise or reject me. Instead, you welcomed me as though I were an angel of God, as though I were Christ Jesus himself!
