'Son' in the Bible

"A son naturally honors his father and a slave respects his master. If I am your father, where is my honor? If I am your master, where is my respect? The Lord who rules over all asks you this, you priests who make light of my name! But you reply, 'How have we made light of your name?'

"They will belong to me," says the Lord who rules over all, "in the day when I prepare my own special property. I will spare them as a man spares his son who serves him.
