'Goest' in the Bible

Only be strong and very courageous, that thou mayest take heed to do according to all the law that Moses my servant commanded thee. Turn not from it to the right or to the left, that thou mayest prosper whithersoever thou goest.

Have I not commanded thee: Be strong and courageous? Be not afraid, neither be dismayed; for Jehovah thy God is with thee whithersoever thou goest.
