Hebrews 11:8, 13, 38

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

All these died in faith, without receiving the promises, but having seen them and having welcomed them from a distance, and having confessed that they were strangers and exiles on the earth.

(men of whom the world was not worthy), wandering in deserts and mountains and caves and holes in the ground.
