Hebrews 11:38 (Amplified Bible) [Men] of whom the world was not worthy — roaming over the desolate places and the mountains, and [living] in caves and caverns and holes of the earth.
Genesis 3:8 And they heard the sound of the Lord God walking in the garden in the cool [afternoon breeze] of the day, so the man and his wife hid and kept themselves hidden from the presence of the Lord God among the trees of the garden. (Amplified Bible)
