John Calvin Commentary Isaiah 48:22

"There is no peace, saith Jehovah, to the wicked." — Isaiah 48:22 (ASV)

There is no peace, says Jehovah to the wicked. These words, “says the Lord,” are included by some commentators in a parenthesis; but we view them as having this connection with what precedes: that the Lord denies wicked people the “peace” of which they are unworthy. This is expressly added so that hypocrites may not, according to their custom, cherish false confidence in these promises, for he declares that the promises do not belong to them, to shut them out altogether from the hope of salvation.

But Isaiah also appears to have had his eye on something else; for since the majority of the people, under the influence of impiety, rejected this blessing, many weak and hesitant individuals might hesitate and be terrified by the opinion of the multitude, just as in our own day we see weak consciences disturbed when they see the majority of people despise the doctrine of salvation.

Seeing many people in danger, he turns their minds away from such a temptation. He does this so they may not be troubled by the multitude of wicked and unbelieving people who reject the grace of God and this prosperous condition, but rather, disregarding those individuals, they may embrace and enjoy this benefit.
