Jeremiah 3:23

Truly in vain is salvation hoped for from the hills, and from
the multitude of mountains
From any natural defence, by hills and mountains encompassing; or from idols worshipped on hills and mountains. So the Targum,

``truly in vain we worship upon the hills, and for no profit are we gathered upon the mountains;''

and to this purpose Jarchi and Kimchi interpret it; or from the multitude of the people, the kingdoms of the world, and the nations of the earth, from whom the Jews have in vain expected salvation and deliverance: truly in the Lord our God is the salvation of Israel;
or, "in the Word of the Lord our God", as the Targum; in Christ, the essential Word of God, is the salvation of all the chosen people, both Jews and Gentiles; it was put into his hands by his Father, and it is wrought out by him; and it resides in him, and it is to be had in him, and in him only, ( Acts 4:12 ) , who is God the Lord, and therefore was able to effect it, and to give it; and hence these repenting ones, discarding all other saviours, apply to him for it.
