'Subjection' in the Bible

For this is what the Lord says,“The products of Egypt and the merchandise of Cush (ancient Ethiopia)And the Sabeans, men of stature,Will come over to you and they will be yours;They will walk behind you, in chains [of subjection to you] they will come over,And they will bow down before you;They will make supplication to you, [humbly and earnestly] saying,‘Most certainly God is with you, and there is no other,No other God [besides Him].’”
