Hebrews 11:8, 13, 38

By faith Abraham, when he was called [by God], obeyed by going to a place which he was to receive as an inheritance; and he went, not knowing where he was going.

All these died in faith [guided and sustained by it], without receiving the [tangible fulfillment of God’s] promises, only having seen (anticipated) them and having welcomed them from a distance, and having acknowledged that they were strangers and exiles on the earth. [Gen 23:4; Ps 39:12]

(people of whom the world was not worthy), wandering in deserts and mountains and [living in] caves and holes in the ground.
