ut obtinerent ascensus montium, per quos via esse poterat ad Jerusalem, et illic custodirent ubi angustum iter esse poterat inter montes.
that they should take possession of the ascents of the mountains, by which there might be any way to Jerusalem, and should keep watch where the way was narrow between the mountains.
Ut obtine ascensus de montes, per que via es pote ad Ierusalem, et ibi custodi ubi angusto itinere es pote inter montes.
