Introduction
Laban is a son of Bethuel, brother of Rebekah, and father of Leah and Rachel, whose household in Paddan-aram (or Aram-Naharaim) is where Jacob takes refuge after fleeing Esau's anger, and where he labours for fourteen years to marry both of Laban's daughters, followed by further years working for and eventually contending with Laban over flocks and wages.
Family
Hosting Jacob
When Jacob arrived at Laban's household seeking refuge and a wife from his mother's own kindred, Laban welcomed him and agreed to let him work seven years for Rachel, the younger of his two daughters, whom Jacob loved.
The deception and Jacob's marriages
On the wedding night, Laban substituted his elder daughter Leah for Rachel, explaining afterward, when Jacob discovered the deception, that local custom required the elder daughter to be married first; Jacob agreed to work a further seven years for Rachel as well, marrying her a week after Leah.
Conflict over wages and flocks
After the birth of Jacob's children, tension grew between Jacob and Laban over wages and the division of flocks, with Laban repeatedly changing the agreed terms, according to Jacob's own later account, though Jacob's flocks nonetheless grew substantially through his own breeding methods, which the text presents as divinely favoured.
Jacob's departure and reconciliation
When Jacob eventually left Laban's household secretly with his wives, children and flocks, Laban pursued him, and the two men, after Laban searched unsuccessfully for household idols his daughter Rachel had secretly taken, reached a formal covenant and boundary marker (Genesis 31), after which they parted ways, Laban returning to his own territory and Jacob continuing toward Canaan.
