"From Kadesh the children of Israel had turned back into the wilderness; and the period of their desert sojourn being ended, they came, “even the whole congregation, into the desert of Zin in the first month: and the people abode in Kadesh.” Numbers 20:1 . PP 410.1"
"Then came the children of Israel, even the whole congregation, into the desert of Zin in the first month: and the people abode in Kadesh; and Miriam died there, and was buried there."
Ellen White directly references Numbers 20:1 in this passage.
"Here Miriam died and was buried. From that scene of rejoicing on the shores of the Red Sea, when Israel went forth with song and dance to celebrate Jehovah's triumph, to the wilderness grave which ended a lifelong wandering—such had been the fate of millions who with high hopes had come forth from Egypt. Sin had dashed from their lips the cup of blessing. Would the next generation learn the lesson? PP 410.2"
"But with many of them God was not well pleased: for they were overthrown in the wilderness."
The EGW passage reflects on the fate of the Israelites who died in the wilderness due to their sin. This directly parallels 1 Corinthians 10:5, which states that God was not pleased with many of them and they were overthrown in the wilderness.
"“For all this they sinned still, and believed not for His wondrous works.... When He slew them, then they sought Him: and they returned and inquired early after God. And they remembered that God was their Rock, and the high God their Redeemer.” Psalm 78:32-35 . Yet they did not turn to God with a sincere purpose. Though when afflicted by their enemies they sought help from Him who alone could deliver, yet “their heart was not right with Him , neither were they steadfast in His covenant. But He, being full of compassion, forgave their iniquity, and destroyed them not: yea, many a time turned He His anger away.... For He remembered that they were but flesh; a wind that passeth away, and cometh not again.” Verses 37-39 . PP 410.3"
"But he, being full of compassion, forgave their iniquity, and destroyed them not: yea, many a time turned he his anger away, and did not stir up all his wrath."
EGW directly quotes and references Psalm 78:38, elaborating on its meaning in the context of the Israelites' behavior.
"For all this they sinned still, and believed not for his wondrous works. Therefore their days did he consume in vanity, and their years in trouble. When he slew them, then they sought him: and they returned and enquired early after God. And they remembered that God was their rock, and the high God their redeemer."
Ellen White directly references Psalms 78:32-35 in this passage.
"When he slew them, then they sought him: and they returned and enquired early after God."
The EGW passage directly quotes and references Psalm 78:34, making it an explicit allusion.
