Laban לבן
Rivka's brother, Yaakov's father-in-law, the archetypal deceiver
Lavan first appears running out to meet Avraham's servant — and the Torah notes that he ran after seeing the ring and the bracelets. That detail is enough to know the man.
Sixty years later his nephew Yaakov arrives, fleeing his brother. Lavan greets him as «my bone and my flesh» and promptly turns him into a labourer. He substitutes the bride at the wedding, excusing himself with local custom; he changes the wages «ten times»; he pursues Yaakov when he finally leaves, and only a warning from Heaven at night restrains him. Even in parting he declares: «The daughters are mine, the sons are mine, the flocks are mine, and all that you see is mine.»
Yet Leah and Rachel came from his house, and with them the whole Jewish people. Tradition holds both truths.
The Passover Haggadah sets him beside Pharaoh: Pharaoh decreed only against the boys, but Lavan sought to uproot everything.
