Then the Amalekites and the Canaanites who lived in that hill country came down and defeated them and pursued them, even to Hormah.

Here is, I. The sudden death of the ten evil spies. While the sentence was passing upon the people, before it was published, they died of the plague before the Lord, Num 14:36, Num 14:37. Now, 1. God hereby showed his particular displeasure against those who sinned and made Israel to sin. (1.) They sinned themselves, in bringing up a slander upon the land of promise.

even unto Hormah--The name was afterwards given to that place in memory of the immense slaughter of the Israelites on this occasion. Next: Numbers Chapter 15

Num 14:39-45 (cf. Deu 1:41-44). The announcement of the sentence plunged the people into deep mourning. But instead of bending penitentially under the judgment of God, they resolved to atone for their error, by preparing the next morning to go to the top of the mountain and press forward into Canaan.
