<p>11:38 <i>(Of whom the world was not worthy), wandering in deserts and mountains and caves and the holes of the earth</i>- The &quot;world&quot; in John's Gospel and at times in Hebrews often refers to the Jewish world. The Jewish world had turned away from God and His Son, and the fact the faithful listed so far were largely Jews meant that the Jewish world was not worthy of them. This was another warning to the Hebrews not to return to Judaism and the Jewish world. It was faithless Israel who wandered in deserts; but for some, they did so in faith in the fulfilment of the promises to Abraham, that at the end of their desert wandering there would be a promised land. David's wandering in deserts and mountains under persecution was motivated by faith in the promise that somehow, God's Kingdom would be established in Israel and the ancient promises come true, as well as those given to him personally. The possibility of a reference to David is strengthened by the next phrase about living in caves and holes. For identical language is found in 1 Sam. 13:6 concerning Israel's pining away when under attack by the Philistines. Yet some did so in faith that the Abrahamic promises would be fulfilled, even though it seemed at the time that Philistine domination was never going to permit that. Likewise &quot;The children of Israel made them the dens ('dry river channels') which are in the mountains, and caves, and strong holds&quot; (Jud. 6:2). Some of the Israelites who fled to the dens and caves in Jud. 6:2 are described as heroes of faith because of their faith that somehow, enemy domination would and must end because of the implications of the promises to Abraham. And yet their domination by the Philistines was a result of their idolatry. They were idolatrous, and yet some had faith; and it was this faith which was perceived by God. &nbsp;</p>
