Numbers 22:24

The angel then stationed himself in a pass of the vineyards where walls (גּדר, vineyard walls, Isa 5:5) were on both sides, so that the animal, terrified by the angel, pressed against the wall, and squeezed Balaam's foot against the wall, for which Balaam smote her again.

At this chapter begins the famous story of Balak and Balaam, their attempt to curse Israel, and the baffling of that attempt; God's people are long afterwards told to remember what Balak the king of Moab consulted, and what Balaam the son of Beor answered him, that they might know the righteousness of the Lord, Mic 6:5. In this chapter we have, I. Balak's fear of Israel, and the plot he had to get them cursed (Num 22:1-4). II. The embassy he sent to Balaam, a conjurer, to fetch him for that purpose, and the disappointment he met with in the first embassy (Num 22:5-14). III. Balaam's coming to him upon his second message (Num 22:15-21). IV. The opposition Balaam met with by the way (Num 22:22-35). V. The interview at length between Balak and Balaam (Num 22:36, etc.).
