Charles Ellicott Commentary Genesis 29:13

"And it came to pass, when Laban heard the tidings of Jacob his sister`s son, that he ran to meet him, and embraced him, and kissed him, and brought him to his house. And he told Laban all these things." — Genesis 29:13 (ASV)

Laban ... ran to meet him, and embraced him. —Rachel told her father, because it was a matter simply of the hospitable reception of a relative, and not such news as Rebekah had run to tell those of her mother’s house. And to Laban the news must have been most welcome, as he now recalled that seventy-seven years ago, he had seen his dear sister depart to marry the son of the distant sheik.

It seems strange, however, that the daughters of this old man should be so young. Either they must have been the children of a wife of his old age, or his granddaughters, but regarded as his own because their father was dead. As Laban’s sons are not mentioned until Genesis 31:1, probably on account of their youth, the former is the more probable explanation.
