Matthew Poole and continuators on Genesis 14:14

14 And when Abram heard that his Brother was taken Captive; he armed his trained Servants born in his own house, three hundred and eighteen, and pursued them unto Dan .

(i. e.) Whom he had disciplined and instructed both in Religion and in the Military Art too, both which were necessary to make them good Souldiers, 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.

This is commonly thought to be a Town then called Leshem, Ios. 19. 47. or Laish, Iudg. 18. 7. and afterwards Dan. See Iudg. 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 Iordan had its Name.
