   In James 1:8, the nominative masculine adjective characterizes the double-minded man in the clause about all his ways; the APB renders the verse, “A double-minded man is restless in all his ways.” In James 3:8, the nominative neuter form characterizes the tongue as an evil in the clause saying that no human can tame it; the APB renders it, “it is a restless evil, full of deadly poison.”

In the Anselm Project Bible: The APB uses “restless” in both James 1:8 and James 3:8, once of the double-minded man and once of the tongue as an evil. This repetition confirms the verses' presentation without isolating every detail of the adjective's contribution.
