"Then taking a boat with His disciples, He crossed the lake to Magdala, at the southern end of the plain of Gennesaret. In the border of Tyre and Sidon His spirit had been refreshed by the confiding trust of the Syrophoenician woman. The heathen people of Decapolis had received Him with gladness. Now as He landed once more in Galilee, where His power had been most strikingly manifested, where most of His works of mercy had been performed, and His teaching given, He was met with contemptuous unbelief. DA 405.1"
"Then began he to upbraid the cities wherein most of his mighty works were done, because they repented not:"
Both passages discuss Jesus' ministry in Galilee and the lack of repentance or belief despite the miracles performed there. The EGW passage provides more context, but the thematic connection is clear.
"A deputation of Pharisees had been joined by representatives from the rich and lordly Sadducees, the party of the priests, the skeptics and aristocracy of the nation. The two sects had been at bitter enmity. The Sadducees courted the favor of the ruling power in order to maintain their own position and authority. The Pharisees, on the other hand, fostered the popular hatred against the Romans, longing for the time when they could throw off the yoke of the conqueror. But Pharisee and Sadducee now united against Christ. Like seeks like; and evil, wherever it exists, leagues with evil for the destruction of the good. DA 405.2"
"For they have consulted together with one consent: they are confederate against thee:"
Both passages highlight the unity of disparate groups against a common target. In Psalms, it's against God; in EGW, it's against Christ. The principle of evil uniting against good is the parallel.
