1 Corinthians 10:5

5.But many of them. We have now the reason why the Apostle has premised these things — that we might not claim for ourselves any dignity or excellence above them, but might walk in humility and fear, for thus only shall we secure, that we have not been favored in vain with the light of truth, and with such an abundance of gracious benefits. “God,” says he, “had chosen them all as his people, but many of them fell from grace. Let us, therefore, take heed, lest the same thing should happen to us, being admonished by so many examples, for God will not suffer that to go unpunished in us, which he punished so severely in them. ”

Here again it is objected: “If it is true, that hypocrites and wicked persons in that age ate spiritual meat, do unbelievers in the present day partake of the reality in the sacraments?” Some, afraid lest the unbelief of men should seem to detract from the truth of God, teach that the reality is received by the wicked along with the sign. This fear, however, is needless, for the Lord offers, it is true, to the worthy and to the unworthy what he represents, but all are not capable of receiving it. In the meantime, the sacrament does not change its nature, nor does it lose anything of its efficacy. Hence the manna, in relation to God, was spiritual meat even to unbelievers, but because the mouth of unbelievers was but carnal, they did not eat what was given them. The fuller discussion, however, of this question I reserve for the 11th Chapter.

For they were overthrown. Proof is here furnished, by adducing a token, that they did not please God — inasmuch as he exercised his wrath upon them with severity, (539) and took vengeance on their ingratitude. Some understand this as referring to the whole of the people that died in the desert, with the exception of only two — Caleb and Joshua. (Numbers 14:29.) I understand him, however, as referring merely to those, whom he immediately afterwards makes mention of in different classes.
