Genesis 29:14

He armed his trained servants, whom he had disciplined and instructed both in religion and in the military art too, both which were necessary to make them good soldiers, that they might both fight with skill and courage, and also rely upon God, and engage his assistance; which was now especially necessary, when so small a party were to engage against so numerous an army. Dan is commonly thought to be a town then called Leshem, Joshua 19:47, or Laish, Judges 18:7, and afterwards Dan; see Judges 18:7,29; so it is an anticipation. But it may be doubted whether this was a city; or if it were, whether it were not another town called by the same name, which was frequent in those parts. And some think this is not a town, but the very fountain of Dan, whence Jordan had its name.
