And when Balak heard that Balaam was come,.... Messengers being sent to acquaint him with it, either by Balaam, or by the princes:

he went out to meet him; overjoyed at the news that his princes had succeeded, and to show him respect, and do him honour, and all to encourage him to do his utmost for him:

unto a city of Moab, which is in the border of Arnon, which is in the utmost coast; by the situation of it, being on the border of the river Arnon, which river was in the extreme parts of Moab, and divided between the Moabites and Amorites, it is generally thought to be the city Ar, called "Ar of Moab", see Numbers 21:13, and the king coming to meet Balaam so far as the uttermost border of his dominions showed the greater respect to him.

Reception of Balaam by the King of the Moabites. - Numbers 22:36, Numbers 22:37. As soon as Balak heard of Balaam's coming, he went to meet him at a city on the border of the Arnon, which flowed at the extreme (north) boundary (of the Moabitish territory), viz., at Areopolis (see at Numbers 21:15), probably the capital of the kingdom at one time, but now reduced to a frontier town, since Sihon the Amorite had taken all the land as far as the Arnon; whilst Rabbah, which was farther south, had been selected as the residence of the king. By coming as far as the frontier of his kingdom to meet the celebrated soothsayer, Balak intended to do him special honour. But he would not help receiving him with a gentle reproof for not having come at his first invitation, as if he, the king, had not been in a condition to honour him according to his merits.

And when Balak heard that Balaam was come, he went out to meet him unto a city of Moab, which is in the {r} border of Arnon, which is in the utmost coast.

(r) Near the place where the Israelites camped.

22:36 In the utmost coast - Not far from the camp of the Israelites, whom he desired him to curse.

36, 37. when Balak heard that Balaam was come, he went out to meet him-Politeness requires that the higher the rank of the expected guest, greater distance is to be gone to welcome his arrival.

22:36-41 Balak has now nothing to complain of, but that Balaam did not come sooner. Balaam bids Balak not depend too much upon him. He seems to speak with vexation; but is really as desirous to please Balak, as ever he had pretended to be to please God. See what need we have to pray every day, Our Father which art in heaven, lead us not into temptation. Let us be jealous over our own hearts, seeing how far men may go in the knowledge of God, and yet come short of Divine grace.
