"Chapter 20—Joseph in Egypt This chapter is based on Genesis 39 to 41 . Meanwhile, Joseph with his captors was on the way to Egypt. As the caravan journeyed southward toward the borders of Canaan, the boy could discern in the distance the hills among which lay his father's tents. Bitterly he wept at thought of that loving father in his loneliness and affliction. Again the scene at Dothan came up before him. He saw his angry brothers and felt their fierce glances bent upon him. The stinging, insulting words that had met his agonized entreaties were ringing in his ears. With a trembling heart he looked forward to the future. What a change in situation—from the tenderly cherished son to the despised and helpless slave! Alone and friendless, what would be his lot in the strange land to which he was going? For a time Joseph gave himself up to uncontrolled grief and terror. PP 213"
"And Joseph was brought down to Egypt; and Potiphar, an officer of Pharaoh, captain of the guard, an Egyptian, bought him of the hands of the Ishmeelites, which had brought him down thither."
EGW references Genesis 39-41 and describes the events of Genesis 39:1.
"hours that which years might not otherwise have taught him. His father, strong and tender as his love had been, had done him wrong by his partiality and indulgence. This unwise preference had angered his brothers and provoked them to the cruel deed that had separated him from his home. Its effects were manifest also in his own character. Faults had been encouraged that were now to be corrected. He was becoming self-sufficient and exacting. Accustomed to the tenderness of his father's care, he felt that he was unprepared to cope with the difficulties before him, in the bitter, uncared-for life of a stranger and a slave. PP 213.2"
"He that delicately bringeth up his servant from a child shall have him become his son at the length."
While not a direct quote, the principle of spoiling a child through indulgence leading to negative consequences aligns with the proverb.
"Then his thoughts turned to his father's God. In his childhood he had been taught to love and fear Him. Often in his father's tent he had listened to the story of the vision that Jacob saw as he fled from his home an exile and a fugitive. He had been told of the Lord's promises to Jacob, and how they had been fulfilled—how, in the hour of need, the angels of God had come to instruct, comfort, and protect him. And he had learned of the love of God in providing for men a Redeemer. Now all these precious lessons came vividly before him. Joseph believed that the God of his fathers would be his God. He then and there gave himself fully to the Lord, and he prayed that the Keeper of Israel would be with him in the land of his exile. PP 213.3"
"And, behold, I am with thee, and will keep thee in all places whither thou goest, and will bring thee again into this land; for I will not leave thee, until I have done that which I have spoken to thee of."
The EGW passage describes Joseph recalling his father's stories about Jacob's encounter with God, which directly relates to the promise in Genesis 28:15. The passage amplifies the idea of God's presence and protection, echoing the promise made to Jacob.
