Римлянам 3:4

God forbid--literally, "Let it not be," that is, "Away with such a thought"--a favorite expression of our apostle, when he would not only repudiate a supposed consequence of his doctrine, but express his abhorrence of it. "The Scriptures do not authorize such a use of God's name as must have been common among the English translators of the Bible" [HODGE]. yea, let God be--held true, and every man a liar--that is, even though it should follow from this that every man is a liar. when thou art judged--so in Psa 51:4, according to the Septuagint; but in the Hebrew and in our version, "when thou judgest." The general sentiment, however, is the same in both--that we are to vindicate the righteousness of God, at whatever expense to ourselves.

The apostle, in this chapter, carries on his discourse concerning justification. He had already proved the guilt both of Gentiles and Jews. Now in this chapter, I. He answers some objections that might be made against what he had said about the Jews (Rom 3:1-8). II. He asserts the guilt and corruption of mankind in common, both Jews and Gentiles (Rom 3:9-18). III. He argues thence that justification must needs be by faith, and not by the law, which he gives several reasons for (Rom 3:19 to the end). The many digressions in his writings render his discourse sometimes a little difficult, but his scope is evident.

3:4 Of course not! The Greek mē genoito is an emphatic negation, popular in the diatribe style that Paul uses here and in several other passages in Romans (see 3:6, 31; 6:2, 15; 7:7, 13; 9:14; 11:1, 11). • As the Scriptures say: Paul quotes Ps 51:4, where David confessed his sin in having an adulterous relationship with Bathsheba (see 2 Sam 11:1-27). God punished David, and David admitted that God was proved right and would win his case in court—his punishment was entirely just. God is faithful to what he has said in the past—his entire revelation—and his words warn of punishment for sin even as they promise reward for obedience.
