Galatians 4:1
Patriarchal Greek New Testament (1904) · Berean Standard Bible
Λέγω δέ, ἐφ᾽ ὅσον χρόνον ὁ κληρονόμος νήπιός ἐστιν, οὐδὲν διαφέρει δούλου, κύριος πάντων ὤν,
What I am saying is that as long as the heir is a child, he is no different from a slave, although he is the owner of everything.
