'Loyal' in the Bible

But now your kingdom will not continue! The Lord has sought out for himself a man who is loyal to him and the Lord has appointed him to be leader over his people, for you have not obeyed what the Lord commanded you."

You must be loyal to your servant, for you have made a covenant with your servant in the Lord's name. If I am guilty, you yourself kill me! Why bother taking me to your father?"
