In Genesis 31:53, Laban sets up a boundary marker between his land and Jacob's and says:
The God of Abraham and the God of Nahor, the God of their father, judge between us.
Apparently some translations take the God of Abraham to be synonymous with the God of Nahor and the God of their father, while others see this as referring to three gods or more. I can see arguments for both.
On the one hand, just earlier in the chapter we read about Rachel stealing Laban's household gods, implying that he is essentially pagan, believing in many gods - and likely so also then his fathers.
On the other hand, the first utterance of Laban — in Genesis 24:31 — suprisingly uses the divine name: "Come, you who are blessed by the LORD." This would perhaps(?) suggest that Laban was already familiar with the God of Abraham, and therefore perhaps also were Nahor and Terah.
Which is the right way to understand this passage?
