"Eliezer would not partake of food until he had told his errand, his prayer at the well, with all the circumstances attending it. Then he said, “And now, if ye will deal kindly and truly with my master, tell me: and if not, tell me; that I may turn to the right hand, or to the left.” The answer was, “The thing proceedeth from the Lord: we cannot speak unto thee bad or good. Behold, Rebekah is before thee; take her, and go, and let her be thy master's son's wife, as the Lord hath spoken.” PP 173.2"
"And now if ye will deal kindly and truly with my master, tell me: and if not, tell me; that I may turn to the right hand, or to the left."
The EGW passage directly quotes Genesis 24:49, making it an explicit allusion. The context is also the same, Eliezer seeking a wife for Isaac.
"After the consent of the family had been obtained, Rebekah herself was consulted as to whether she would go to so great a distance from her father's house, to marry the son of Abraham. She believed, from what had taken place, that God had selected her to be Isaac's wife, and she said, “I will go.” PP 173.3"
"And they called Rebekah, and said unto her, Wilt thou go with this man? And she said, I will go."
EGW directly quotes and elaborates on the biblical passage.
"The servant, anticipating his master's joy at the success of his mission, was impatient to be gone; and with the morning they set out on the homeward journey. Abraham dwelt at Beersheba, and Isaac, who had been attending to the flocks in the adjoining country, had returned to his father's tent to await the arrival of the messenger from Haran. “And Isaac went out to meditate in the field at the eventide: and he lifted up his eyes, and saw, and, behold, the camels were coming. And Rebekah lifted up her eyes, and when she saw Isaac, she lighted off the camel. For she had said unto the servant, What man is that that walketh in the field to meet us? And the servant had said, It is my master: therefore she took a veil, and covered herself. And the servant told Isaac all things that he had done. 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.” PP 173.4"
"And Isaac went out to meditate in the field at the eventide: and he lifted up his eyes, and saw, and, behold, the camels were coming."
EGW directly quotes and elaborates on the biblical passage.
"Abraham had marked the result of the intermarriage of those who feared God and those who feared Him not, from the days of Cain to his own time. The consequences of his own marriage with Hagar, and of the marriage connections of Ishmael and Lot, were before him. The lack of faith on the part of Abraham and Sarah had resulted in the birth of Ishmael, the mingling of the righteous seed with the ungodly. The father's influence upon his son was counteracted by that of the mother's idolatrous kindred and by Ishmael's connection with heathen wives. The jealousy of Hagar, and of the wives whom she chose for Ishmael, surrounded his family with a barrier that Abraham endeavored in vain to overcome. PP 173.5"
"That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose."
Both passages discuss the negative consequences of intermarriage between those who follow God and those who do not. EGW draws a parallel between Genesis 6:2 and Abraham's experiences.
