Charles Ellicott Commentary Genesis 24:50

"Then Laban and Bethuel answered and said, The thing proceedeth from Jehovah. We cannot speak unto thee bad or good." — Genesis 24:50 (ASV)

Laban and Bethuel. —See Note on Genesis 24:28. Even when mentioned so late, the father is placed after the brother; and we need no further explanation for this than that by polygamy the father was estranged from his own children, while each separate family held very closely together. Thus when Dinah was wronged, it was two of her mother’s sons, Simeon and Levi, who avenged her (Genesis 34:13–25); and so it was Absalom who avenged Tamar (2 Samuel 13:22). Still, Bethuel’s consent was finally necessary; but as soon as it was given, all active arrangements were left to the mother and Laban (Genesis 24:53–55), and Bethuel is mentioned no more.
