"Chapter 36—The Last King of Judah Zedekiah at the beginning of his reign was trusted fully by the king of Babylon and had as a tried counselor the prophet Jeremiah. By pursuing an honorable course toward the Babylonians and by paying heed to the messages from the Lord through Jeremiah, he could have kept the respect of many in high authority and have had opportunity to communicate to them a knowledge of the true God. Thus the captive exiles already in Babylon would have been placed on vantage ground and granted many liberties; the name of God would have been honored far and wide; and those that remained in the land of Judah would have been spared the terrible calamities that finally came upon them.

"And seek the peace of the city whither I have caused you to be carried away captives, and pray unto the Lord for it: for in the peace thereof shall ye have peace."
Both passages emphasize seeking the well-being of the place of exile/captivity. EGW expands on the potential benefits of Zedekiah's actions, echoing the sentiment of Jeremiah 29:7.
"Through Jeremiah, Zedekiah and all Judah, including those taken to Babylon, were counseled to submit quietly to the temporary rule of their conquerors. It was especially important that those in captivity should seek the peace of the land into which they had been carried. This, however, was contrary to the inclinations of the human heart; and Satan, taking advantage of the circumstances, caused false prophets to arise among the people, both in Jerusalem and in Babylon, who declared that the yoke of bondage would soon be broken and the former prestige of the nation restored. PK 440.2"
"For thus saith the Lord of hosts, the God of Israel; Let not your prophets and your diviners, that be in the midst of you, deceive you, neither hearken to your dreams which ye cause to be dreamed."
Both passages discuss false prophets deceiving the people during the time of Jeremiah and the Babylonian exile. EGW amplifies the context and implications of Jeremiah's warning.
