NET

21 “Go, ask the Lord for me and for those who remain in Israel and Judah about the words of this scroll that has been discovered. For the Lord’s great fury has been ignited against us, because our ancestors did not obey the word of the Lord by living according to all that is written in this scroll.”

Darby

21 Go, inquire of Jehovah for me, and for them that are left in Israel and in Judah, concerning the words of the book which is found; for great is the wrath of Jehovah that is poured out upon us, because our fathers have not kept the word of Jehovah, to do according to all that is written in this book.

KJV

21 Go, enquire of the LORD for me, and for them that are left in Israel and in Judah, concerning the words of the book that is found: for great [is] the wrath of the LORD that is poured out upon us, because our fathers have not kept the word of the LORD, to do after all that is written in this book.
