Thus saith the LORD the maker thereof, the LORD that formed it, to establish it; the LORD is his name;
The Lord, the maker thereof - rather, the Doer of it-namely, of that which Jeremiah is about to prophesy, the restoration of Israel, an act which is thought now impossible, but which the Almighty will effect.
The Lord that formed it - namely, Jerusalem (Jeremiah 32:44). (Calvin.) Rather, that formed - i:e., moulds His purpose into due shape for execution (Isaiah 37:26, "Of ancient times I have formed it").
The Lord is his name - Hebrew, 'Yahweh' (Exodus 3:14-15).
