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, [1] 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.

Footnotes

1 - "Il a fait une horrible vengence sur eux;" -- "He inflicted dreadful vengeance upon them."

But with many of them - That is, with their conduct. They rebelled and sinned, and were destroyed. The design of the apostle here is, to remind them that although they enjoyed so many privileges, yet they were destroyed; and thus to admonish the Corinthians that their privileges did not constitute an absolute security from danger, and that they should be cautious against the indulgence of sin. The phrase rendered here "with many" ἐν τοῖς πλείων en tois pleiōn should have been rendered "with most of them," literally" with the many; and it means that with the greater part of them God was not well pleased; that is, he was pleased with but few of them.
Was not well pleased - Was offended with their ingratitude and rebellion.
For they were overthrown - That is, by the pestilence, by wars, or died by natural and usual diseases, so that they did not reach the land of Canaan. But two men of that generation, Caleb and Joshua, were permitted to enter the land of promise; Numbers 14:29-30.

They were overthrown in the wilderness - And yet All these persons were under the cloud - All passed through the sea - All were baptized into Moses in the cloud and in the sea - All ate the same spiritual meat - All drank the same spiritual drink, for they were made partakers of the spiritual Rock, Christ. Nothing can be a more decisive proof than this that people, who have every outward ordinance, and are made partakers of the grace of our Lord Jesus, may so abuse their privileges and grieve the Spirit of God as to fall from their state of grace, and perish ever lastingly. Let those who are continually asserting that this is impossible, beware lest they themselves, if in a state of grace, become, through their overmuch security, proofs in point of the possibility of ending in the flesh, though they began in the Spirit. Reader, remember who said, Ye shall not surely die; and remember the mischiefs produced by a belief of his doctrine.

But with many of them God was not well pleased,.... As he is with none but those that are in Christ; and with none of the services of men, but what are done in faith, which become acceptable to him through Jesus Christ; for in him only persons and services are accepted with God; and this was the way of acceptance in the Old, as in the New Testament dispensation: how many of the Jewish fathers God was not well pleased with, or took no delight in, but hated and abhorred, which is the sense of the phrase here, whether they were the greatest part or not, is not certain; however, they were not all, excepting Joshua and Caleb, as some interpreters understand it; for not all that died in the wilderness were out of the special grace and favour of God, witness Moses, Aaron, Miriam, and, it is to be supposed and hoped, hundreds and thousands more; but the apostle has respect to such who were the instances of God's direful vengeance and displeasure, as appears from the reason given;
for they were overthrown in the wilderness: he does not say merely that they died there, for many with whom God was well pleased died there; but these, their carcasses fell in the wilderness, being stricken, thrown down, and overthrown by the immediate hand of God; they did not die a common death, according to the ordinary course of nature; but by the plague, or by the sword, or by fire from heaven, or by fiery serpents, or by a destroying angel, or by one judgment or another, as hereafter mentioned.

But--though they had so many tokens of God's presence.
many of them--rather, "the majority of them"; "the whole part." All except Joshua and Caleb of the first generation.
not--in the Greek emphatically standing in the beginning of the sentence: "Not," as one might have naturally expected, "with the more part of them was," &c.
God--whose judgment alone is valid.
for--the event showed, they had not pleased God.
overthrown--literally, "strewn in heaps."
in the wilderness--far from the land of promise.

Yet - Although they had so many tokens of the divine presence. They were overthrown - With the most terrible marks of his displeasure.
