'Though' in the Bible

And if a soul sin, and commit any of these things which are forbidden to be done by the commandments of the LORD; though he wist it not, yet is he guilty, and shall bear his iniquity.

And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.

And if thy brother be waxen poor, and fallen in decay with thee; then thou shalt relieve him: yea, though he be a stranger, or a sojourner; that he may live with thee.
