"When Moses made known to Israel the will of God concerning them, they seemed sincerely to repent of their sinful conduct. But the Lord knew that they sorrowed because of the result of their evil course, rather than from a deep sense of their ingratitude and disobedience. But their repentance came too late; the just anger of God was awakened, and their doom was pronounced, from which there was no reprieve. When they found that the Lord would not relent in His decree, their self-will again arose, and they declared that they would not return into the wilderness. 4T 153.1"
"(Now the Amalekites and the Canaanites dwelt in the valley.) To morrow turn you, and get you into the wilderness by the way of the Red sea."
EGW's passage discusses Israel's superficial repentance and subsequent rebellion, referencing their refusal to return to the wilderness. Numbers 14:25 directly commands them to return to the wilderness. The EGW passage amplifies the narrative and draws a parallel to later situations.
