'Thereof' in the Bible

But we built the wall; and all the wall was joined together to the half thereof; for the people had a mind to work.

Behold, we are servants this day, and the land that thou gavest unto our fathers to eat the fruit thereof and the good thereof, behold, we are bondmen in it.

Remember me, O my God, concerning this, and wipe not out my good deeds which I have done for the house of my God, and for the charges thereof!
