"This chapter is based on Joshua 1 to 5:12 . The Israelites deeply mourned for their departed leader, and thirty days were devoted to special services in honor of his memory. Never till he was taken from them had they so fully realized the value of his wise counsels, his parental tenderness, and his unswerving faith. With a new and deeper appreciation they recalled the precious lessons he had given while still with them. PP 481.1"
"And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended."
The EGW passage directly references and expands upon the mourning period for Moses described in Deuteronomy 34:8.
"Moses was dead, but his influence did not die with him. It was to live on, reproducing itself in the hearts of his people. The memory of that holy, unselfish life would long be cherished, with silent, persuasive power molding the lives even of those who had neglected his living words. As the glow of the descending sun lights up the mountain peaks long after the sun itself has sunk behind the hills, so the works of the pure, the holy, and the good shed light upon the world long after the actors themselves have passed away. Their works, their words, their example, will forever live. “The righteous shall be in everlasting remembrance.” Psalm 112:6 . PP 481.2"
"Surely he shall not be moved for ever: the righteous shall be in everlasting remembrance."
Ellen White directly references Psalms 112:6 in this passage.
"By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh."
Both passages discuss the lasting impact and remembrance of righteous individuals after their death. The EGW passage uses Psalm 112:6 directly, but the connection to Hebrews 11:4 is more thematic.
"While they were filled with grief at their great loss, the people knew that they were not left alone. The pillar of cloud rested over the tabernacle by day, and the pillar of fire by night, an assurance that God would still be their guide and helper if they would walk in the way of His commandments. PP 481.3"
"And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night:"
The EGW passage explicitly mentions the pillar of cloud and fire guiding the Israelites, directly alluding to Exodus 13:21.
