Romans 10:5 - Wesley's Explanatory Notes

For Moses describeth the only righteousness which is attainable by the law, when he saith, The man who doeth these things shall live by them — that is, he that perfectly keeps all these precepts in every point, he alone may claim life and salvation by them. But this way of justification is impossible to any who have ever transgressed any one law in any point. Leviticus 18:5
