Charles H. Spurgeon on Psalms 106:28

They joined themselves also unto Baalpeor. Ritualism led on to the adoration of false gods. If we choose a false way of worship we shall, ere long, choose to worship a false god. This abomination of the Moabites was an idol in whose worship women gave up their bodies to the most shameless lust. Think of the people of a holy God coming down to this. And ate the sacrifices of the dead. In the orgies with which the Baalites celebrated their detestable worship Israel joined, partaking even in their sacrifices as earnest inner court worshippers, though the gods were but dead idols. Perhaps they assisted in necromantic rites which were intended to open a correspondence with departed spirits, thus endeavouring to break the seal of God's providence, and burst into the secret chambers which God has shut up. Those who are weary of seeking the living God have often shown a hankering after dark sciences, and have sought after fellowship with demons and spirits. To what strong delusions those are often given up who cast off the fear of God! This remark is as much needed now as in days gone by.
