'Son' in the Bible

“‘A son honors his father, and a servant his master. Then if I am a Father, where is My honor? And if I am a Master, where is the [reverent] fear and respect due Me?’ says the Lord of hosts to you, O priests, who despise My name. But you say, ‘How and in what way have we despised Your name?’

“They will be Mine,” says the Lord of hosts, “on that day when I publicly recognize them and openly declare them to be My own possession [that is, My very special treasure]. And I will have compassion on them and spare them as a man spares his own son who serves him.”
