"Then Abraham saw “a ram caught in a thicket,” and quickly bringing the new victim, he offered it “in the stead of his son.” In his joy and gratitude Abraham gave a new name to the sacred spot—“Jehovah-jireh,” “the Lord will provide.” PP 153.1"
"And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son."
The EGW passage directly quotes and references Genesis 22:13, describing the ram caught in the thicket and Abraham's subsequent offering. It's a clear and direct allusion to the biblical text.
"On Mount Moriah, God again renewed His covenant, confirming with a solemn oath the blessing to Abraham and to his seed through all coming generations: “By myself have I sworn, saith Jehovah, for because thou hast done this thing, and hast not withheld thy son, thine only son, that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the seashore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed My voice.” PP 153.2"
"And said, By myself have I sworn, saith the Lord, for because thou hast done this thing, and hast not withheld thy son, thine only son:"
The EGW passage directly quotes Genesis 22:16.
"Abraham's great act of faith stands like a pillar of light, illuminating the pathway of God's servants in all succeeding ages. Abraham did not seek to excuse himself from doing the will of God. During that three days’ journey he had sufficient time to reason, and to doubt God, if he was disposed to doubt. He might have reasoned that the slaying of his son would cause him to be looked upon as a murderer, a second Cain; that it would cause his teaching to be rejected and despised; and thus destroy his power to do good to his fellow men. He might have pleaded that age should excuse him from obedience. But the patriarch did not take refuge in any of these excuses. Abraham was human; his passions and attachments were like ours; but he did not stop to question how the promise could be fulfilled if Isaac should be slain. He did not stay to reason with his aching heart. He knew that God is just and righteous in all His requirements, and he obeyed the command to the very letter. PP 153.3"
"By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,"
Both passages discuss Abraham's willingness to sacrifice Isaac as an act of faith. The EGW passage expands on the internal struggle Abraham might have faced, while Hebrews 11:17 focuses on the faith aspect.
