“(Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth.”
King James Version (KJV)
11:38 Of whom the world was not worthy - It did not deserve so great a blessing. They wandered - Being driven out from men.
Heb 11:38 Of whom the world was not worthy. When it rejects the good it shows its unworthiness. They wandered in deserts, etc. To hide from persecutors.
