20 He said, "You shall not pass through." Edom came out against him with many people, and with a strong hand.

The Israelites, without awaiting at Kadesh the return of their ambassador, commenced their eastward march. At the tidings of their approach the Edomites mustered their forces to oppose them; and on crossing the Arabah they found their ascent through the mountains barred. The notice of this is inserted here to complete the narrative; but in order of time it comes after the march described in Numbers 20:22.
And he said, thou shall not go through,.... Which is an absolute and peremptory denial:
and Edom came out against him with much people, and with a strong hand; the king raised the militia of his country, and came at the head of a powerful army to hinder their passing into it; being fearful and jealous, lest such a large body as they were should seize on his country, or spoil it, not relying on their promises; and this might arise also from the old grudge of Esau against Jacob, and which continued in his posterity, and might now be revived upon their going to Canaan to possess the earthly blessing conferred on Jacob and his seed: however, it seems, though the Edomites would not let Israel pass through their country, yet they furnished them with food and drink for their money, Deuteronomy 2:28.
To give emphasis to his refusal, Edom went against Israel "with much people and with a strong hand," sc., when they approached its borders. This statement, as well as the one in Numbers 20:21, that Israel turned away before Edom, anticipates the historical order; for, as a matter of course, the Edomites cannot have come at once with an army on the track of the messengers, for the purpose of blocking up the road through the Wady Murreh, which runs along the border of its territory to the west of the Arabah.
