Albert Barnes Commentary Deuteronomy 8:15

"who led thee through the great and terrible wilderness, [wherein were] fiery serpents and scorpions, and thirsty ground where was no water; who brought thee forth water out of the rock of flint;" — Deuteronomy 8:15 (ASV)

Render: "Who brought you through that great and terrible wilderness, the fiery serpent and the scorpion, and the dry land where are no waters." On the fiery serpents see Numbers 21:6 note.
