Hebrews 5:13 - Coke's Commentary on the Holy Bible

In the word of righteousness:— Every one who is unacquainted with the word of righteousness, is here called a babe: the thing intended is, that whosoever is ignorant of the righteousness of God without the law, which is witnessed by the law and the prophets, even the righteousness of God which is by faith in Christ Jesus, unto all and upon all that believe, is only fit to be begun with, and to be taught the first elements of the oracles of God. This is sometimes called the righteousness of God. Romans 3:22 sometimes the righteousness which is of faith, Romans 9:30. The word of righteousness means, the doctrine of our being treated as righteous, in consequence of our faith in Christ. See Romans 3:24. 2 Corinthians 5:19. It is called the righteousness of God, as it is the method that he has taken wherein to treat mankind; and as faith is the thing required as a means of his grace, it is the righteousness of faith, or by faith: and it is called absolutely the word of righteousness, as it is the great principle of the gospel of Christ.
