Few left to the light of nature seem to have conceived the necessity
of repentance, in order to obtain the divine favor. For their sins,
they must somehow, make atonement, and they would then be forgiven,
though they continued to commit them! Mankind have entertained
different ideas of what was necessary to make atonement. The more
common idea hath been, that it was to be done by sacrifice; however
they came by that idea. It probably derived by tradition from the
first family of our race. But there seems to have been a general
mistake respecting the design of sacrifice. By those devoid of
revelation, it hath not been considered as pointing to a divine
sacrifice, but as having in _itself_ an atoning virtue. So it seems to
have been viewed by this Moabitish prince.

Another mistake respecting sacrifices, which hath been common in the
world, is this--That their value depends on their cost to the offerer.
This was a mistake of Balak. If common offerings, and the usual number
of victims would not procure the divine favor and atone for his sins,
he would offer more, and more costly ones--_thousands of rams, and ten
thousands of rivers of oil_! Such a profusion of sacrifices, of the
same kind, or partly so, with those offered by Israel, so many more
they were able, coming out of the wilderness, to offer, he hoped would
prevail to detach from them their God, and buy him so to be his
friend!

But if not, if these were too little, he would sacrifice his
offspring! _Give his first born for his transgression--the fruit of
his body for the sin of his soul_! A sacrifice much more costly, much
more painful, than that of all earthly treasure! Surely such an
offering must prevail!
