Children, obey—in all things:— That is, "which are lawful, or to which the parental authority extends." This must be understood with some such limitation; and there can be no hurt in supplying the sense from Colossians 3:18 with εν κυριω, in the Lord; and so it is expressed, Ephesians 6:1. That is, "as the Lord requires you, and as far as is consistent with your duty to him."
