When the camels had finished drinking, the man took a gold nose-ring weighing a half shekel, and two bracelets for her arms weighing ten gold shekels, and said, “Tell me whose daughter you are. Is there room in your father’s house for us to spend the night?”
On a random historical note, though it is clear that these stories come from older narratives and traditions written down much later, it is interesting that these stories still have features that would have been accurate for the time at which the story took place, millennia before the story was written down. You can see an example here. At the Pennsylvania Museum of Archaeology, you can see artifacts from this area and supposed time (where I have seen with my own eyes the type of jewelry that this would be referring to). From doing that, it really looks like things such as these bracelets and gold rings were used for currency a lot more at this particular time in history. Later on, in a story such as this you would have more references to gold, money, cattle, or more established forms of bartering.
