Римлянам 3:10

As it is written, &c.-- (Psa 14:1-3; Psa 53:1-3). These statements of the Psalmist were indeed suggested by particular manifestations of human depravity occurring under his own eye; but as this only showed what man, when unrestrained, is in his present condition, they were quite pertinent to the apostle's purpose.

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.

3:10-18 The six quotations in these verses, drawn from various parts of the Old Testament, all address human sinfulness. Paul follows the practice of rabbis who gathered together Old Testament texts on similar themes in a practice called pearl-stringing. 3:10-12 This quotation from Pss 14:1-3; 53:1-3 directly supports the argument that all people are under the power of sin.
