2 Kings 22:13

Go ye, inquire of the Lord
Of some of his prophets, as Jeremiah, who began to prophesy in the thirteenth year of Josiah's reign, and had been a prophet five years, ( Jeremiah 1:1 Jeremiah 1:2 ) ,

for me, and for the people, and for all Judah, concerning the words of
this book that is found;
for he observed that this book threatened and foretold not only the captivity of the ten tribes, but of Judah, and of their king; and Jarchi thinks, he had a particular respect to that passage,

the Lord shall bring thee and thy king
( Deuteronomy 28:36 ) and therefore was desirous of knowing what he and his people must do to avert those judgments:

for great is the wrath of the Lord that is kindled against us;
which he concluded from the threatenings denounced:

because that our fathers have not hearkened unto the words of this
book, to do according to all which is written concerning us:
he clearly saw that his ancestors more remote and immediate had been very deficient in observing the laws, commands, and ordinances enjoined them in that book; and therefore feared that what was threatened would fall upon him and his people, who, he was sensible, came short of doing their duty.
