Kommentar zu Könige I 1:42

for thou art a worthy man, and bringest good tidings: It would seem that the intended meaning of "worthy man" is "good man," because the good man does "worthiness" by his kindness, and the way of the good man is to give good tidings, not bad. Or, the intended meaning of "worthy man" is "brave man," because the way of the brave man is always to predict good [results] from words of conflict and war because he is not afraid.
