Thus shall ye say unto them, The gods that have not made the heavens and the earth, even they shall perish from the earth, and from under these heavens.
Shall perish - (Isaiah 2:18, "The idols He shall utterly abolish," namely, "in the day of the Lord of hosts;" Jeremiah 10:12; Zechariah 13:2).
These heavens - the speaker pointing to them with his finger.
Jeremiah 10:12 is a continuation of Jeremiah 10:10, after the interruption of the thread of the discourse in Jeremiah 10:11 (Psalms 136:5-6).
