Zephaniah 1:5

The host of heaven - Sun, moon, planets, and stars. This worship was one of the most ancient and the most common of all species of idolatry; and it had a greater semblance of reason to recommend it. See 2 Kings 23:6 , 2 Kings 23:12 ; Jeremiah 19:13 ; Jeremiah 32:29 .

That swear by the Lord, and that swear by Malcham - Associating the name of an idol with that of the Most High. For Malcham, see on Hosea 4:15 ; (note), and Amos 5:26 ; (note).
