"Those times of change, so fraught with peril to the Israelitish nation, were marked with many messages from Heaven through Jeremiah. Thus the Lord gave the children of Judah ample opportunity of freeing themselves from entangling alliances with Egypt, and of avoiding controversy with the rulers of Babylon. As the threatened danger came closer, he taught the people by means of a series of acted parables, hoping thus to arouse them to a sense of their obligation to God, and also to encourage them to maintain friendly relations with the Babylonian government. PK 423.1"
"And the Lord God of their fathers sent to them by his messengers, rising up betimes, and sending; because he had compassion on his people, and on his dwelling place:"
Both passages highlight God's repeated attempts to communicate with His people through messengers. The EGW passage speaks of messages through Jeremiah, while 2 Chronicles 36:15 describes God sending messengers out of compassion. The connection lies in the persistent communication from God to His people.
"To illustrate the importance of yielding implicit obedience to the requirements of God, Jeremiah gathered some Rechabites into one of the chambers of the temple and set wine before them, inviting them to drink. As was to have been expected, he met with remonstrance and absolute refusal. “We will drink no wine,” the Rechabites firmly declared, “for Jonadab the son of Rechab our father commanded us, saying, Ye shall drink no wine, neither ye, nor your sons forever.” PK 423.2"
"But they said, We will drink no wine: for Jonadab the son of Rechab our father commanded us, saying, Ye shall drink no wine, neither ye, nor your sons for ever:"
The EGW passage directly quotes Jeremiah 35:6, making it a clear and explicit allusion.
