What does Genesis 31:26 mean?

Jacob had fled from Laban in response to Laban's continual abuse. Not only did Laban lie and cheat Jacob when it came to marrying his daughters (Genesis 29:20–28), he attempted to take advantage of Jacob by accepting a ridiculous payment scheme, one which Laban tried to make even more lopsided (Genesis 30:31–36). Unfortunately for Laban, this deal was actually part of God's restoration of Jacob (Genesis 31:10–12), and it backfired spectacularly (Genesis 30:37–43). Seeing Laban's displeasure, Jacob and his wives—Laban's own daughters—agreed to leave abruptly and without notice, heading to Jacob's family in Canaan.

After a three-day delay in hearing news of Jacob's flight, and a seven-day chase, Laban's harsh confrontation of Jacob finally begins. In spite of God's warning to Laban in a dream not to say anything to Jacob, good or bad, Laban has prepared a speech for his lying, fleeing son-in-law. Now he unleashes it.

He begins, ironically, with the same words Jacob said to him on Jacob's wedding night some 13 years earlier: "What have you done?" Laban's first two accusations are that Jacob tricked him in this sudden departure and, worse, that Jacob had carried Laban's two daughters away as if they were captives or prisoners. Laban does not know, yet, that both Rachel and Leah expressed their full support for Jacob's plan to leave Laban and return to his own homeland.
