That I may perform the oath which I have sworn unto your fathers,.... Abraham, Isaac, and Jacob:
to give them a land flowing with milk and honey: that is, abounding with plenty of all kind of provisions; see Exodus 3:8:
as it is this day; the land of Canaan continued to those times a very fruitful country; it was as it was promised it should be, and which was a clear thing; their eyes saw it, and the day bore witness to it:
then answered I, and said; that is, the Prophet Jeremiah, to whom the above order was given:
so be it, O Lord; or, "Amen, Lord" f; either agreeing to publish what the Lord commanded him; or as wishing that the land of Canaan might continue the same fruitful land it was, and the people of the Jews in it, they keeping the words of this covenant; or else as assenting that the curse might fall upon the men that did not observe them, alluding to Deuteronomy 27:15. This is the sense of Abarbinel; Jarchi and Kimchi observe, that the word "Lord" is vocative, and in the language of prayer.
