Verse 15. Led thee through that ... wilderness, wherein were fiery serpents, and scorpions. The part of the desert referred to was after the departure from Horeb (see the notes at Numbers 21:4; Deuteronomy 1:19; also Jeremiah 2:6), by way of the mountain of the Amorites, as they came to Kadesh-barnea. Now, as the whole journey from Horeb to Kadesh occupied eleven days, that portion of the way which included the "great and terrible wilderness" must have been traversed in a shorter time, say 10 days; and assuming a day's journey to have been not more than 10 miles per day, the utmost extent of the fearful region would be 100 miles-a space sufficiently large, it must be acknowledged, for a numerous population to perish in. Large and venomous reptiles are found in great numbers there still, particularly in autumn.
