Charles Ellicott Commentary Numbers 22:7

"And the elders of Moab and the elders of Midian departed with the rewards of divination in their hand; and they came unto Balaam, and spake unto him the words of Balak." — Numbers 22:7 (ASV)

And the elders of Moab and the elders of Midian. —The close alliance that existed between the two nations appears throughout the entire narrative.

The rewards of divination.— Literally, the divinations. Some think the meaning is instruments of divination; but as besorah means not only tidings, but also the reward for tidings (2 Samuel 4:10), so kesamim may mean not only divinations, but also the rewards of divination.
