"Jeremiah called their attention repeatedly to the counsels given in Deuteronomy. More than any other of the prophets, he emphasized the teachings of the Mosaic law and showed how these might bring the highest spiritual blessing to the nation and to every individual heart. “Ask for the old paths, where is the good way, and walk therein,” he pleaded, “and ye shall find rest for your souls.” Jeremiah 6:16 . PK 411.1"
"Thus saith the Lord, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk therein."
Ellen White directly references Jeremiah 6:16 in this passage.
