“One that ruleth well his owne house, hauing his children in subiection with all grauitie.”
1611 King James Version (KJV)
3:4 Having his children in subjection with all seriousness - For levity undermines all domestic authority; and this direction, by a parity of reason, belongs to all parents.
1Ti 3:4 One that ruleth well his own house. This implies that he must be a man of family. Having his children in subjection. He must be a father with obedient children.
