1 Corinthians 10:6

The apostle, having recited their privileges, proceeds here to an account of their faults and punishments, their sins and plagues, which are left upon record for an example to us, a warning against the like sins, if we would escape the like punishments. We must not do as they did, lest we suffer as they suffered. I. Several of their sins are specified as cautions to us; as, 1. We should shun inordinate desires after carnal objects: Not lust after evil things, as they lusted, Co1 10:6. God fed them with manna, but they must have flesh, Num 11:4. They had food for their supply, but, not content with this, they asked meat for their lusts, Psa 106:14. Carnal desires get head by indulgence, and therefore should be observed and checked in their first rise: if once they prevail, and bear sway in us, we know not whither they will carry us. This caution stands first, because carnal appetites indulged are the root and source of much sin. 2. He warns against idolatry (Co1 10:7): Neither be you idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play. The sin of the golden calf is referred to, Exo 32:6. They first sacrificed to their idol, then feasted on the sacrifices, and then danced before it. Though only eating and drinking are mentioned here, yet the sacrifice is supposed.

were--Greek, "came to pass as." our examples--samples to us of what will befall us, if we also with all our privileges walk carelessly. lust--the fountain of all the four other offenses enumerated, and therefore put first (Jam 1:14-15; compare Psa 106:14). A particular case of lust was that after flesh, when they pined for the fish, leeks, &c., of Egypt, which they had left (Num 11:4, Num 11:33-34). These are included in the "evil things," not that they are so in themselves, but they became so to the Israelites when they lusted after what God withheld, and were discontented with what God provided.
