John Chrysostom
Therefore the Apostle continues: "Now these things became types for us" (1 Cor 10:6). As their gifts were types, so their punishments were types.
As Baptism and the mystical table were prefigured, so later events foretold that those unworthy of the gift would undergo punishment. Thus by such examples we might learn to be more temperate.
Therefore he adds: "that we should not be desirers of evil things, as they also desired." As in benefactions the types came first and the truth followed them, so it will be in punishments.
Do you see how he suggests that we shall not only be punished, but far more than those Israelites? For if there were types there, and the truth is here, then the punishments too must be far greater, just as the gifts are.

He first says: "Nor become idolaters, as some of them did, as it is written: 'The people sat down to eat and drink, and rose up to play'" (1 Cor 10:7).
Do you hear how he calls the Corinthians idolaters? Here, however, he only hints at it. Later he proves it.
