Heb. There shall not be to thee another god, or other gods, to wit, idols, which others have, esteem, and worship as gods, and therefore Scripture so calls them by way of supposition, Deuteronomy 32:21 1 Samuel 12:21 1 Corinthians 8:4,5; but thou shalt not have them in any such reputation or veneration, but shalt forsake and abhor them, and cleave unto me alone. Before me, i.e. in my presence, in my house or Church, which you are, where I am especially present; and therefore for you to worship any other god is most impudent idolatry, even as when a woman commits adultery before her husband's face. He may also intimate, that all the idolatry which any of them shall hereafter commit, though never so cunningly and secretly managed, is manifest to his eyes, Psalms 44:20,21. Others translate it with me, or besides me, as it is rendered Matthew 12:30. He forbids the worship of all others, not only in opposition to him, but also in conjunction with him, or subordination to him. See 2 Kings 17:33 Exo 32 Ac 7:41 Revelation 19:10, Revelation 22:8,9.
