"Lessons from the Marriage of Isaac. —Isaac was highly honored by God, in being made inheritor of the promises through which the world was to be blessed; yet when he was forty years of age, he submitted to his father's judgment in appointing his experienced, God-fearing servant to choose a wife for him. And the result of that marriage, as presented in the Scriptures, is a tender and beautiful picture of domestic happiness. “Isaac brought her unto his mother Sarah's tent, and took Rebekah, and she became his wife; and he loved her; and Isaac was comforted after his mother's death.” [ Genesis 24:67 .] CE 228.1"
"And Isaac brought her into his mother Sarah’s tent, and took Rebekah, and she became his wife; and he loved her: and Isaac was comforted after his mother’s death."
Ellen White directly references Genesis 24:67 in this passage.
