With the rewards of divination. קְסָמִים, "soothsayings." Septuagint, τὰ μαντεῖα. Here the soothsayer's wages, which St. Peter aptly calls the wages of unrighteousness. The ease with which, among ignorant and superstitious people, a prophet might become a hired soothsayer is apparent even from the case of Samuel (1 Samuel 9:6-8).
That it should be thought proper to resort to the man of God for information about some lost property, and much more that it should be thought necessary to pay him a fee for the exercise of his supernatural powers, shows, not indeed that Samuel was a soothsayer, for he was a man of rare integrity and independence, but, that Samuel was but little distinguished from a soothsayer in the popular estimation.
If Samuel had learnt to care more for money than for righteousness, he might very easily have become just what Balaam became.
