'Though' in the Bible

What doth it profit, my brethren, though a man say he hath faith, and have not works? can faith save him?

Behold also the ships, which though they be so great, and are driven of fierce winds, yet are they turned about with a very small helm, whithersoever the governor listeth.

So too, though the tongue is a small part of the body, it boasts great things. Consider how large a forest a small fire ignites.

You have condemned and murdered the one who is righteous, even though he did not rebel against you.
