Jeremiah 11:5

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 ) ( Deuteronomy 6:3 ) ( 8:7-9 ) : 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" ^F6; 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 27:15-26 ) . This is the sense of Abarbinel; Jarchi and Kimchi observe, that the word "Lord" is vocative, and in the language of prayer.
