ציטירנדיקער פּירוש אויף מלכים א 2:2

ה' איש מלחמה means The Lord is a Master of war; just as, (Ruth 1:3) “the איש (i. e. the master) of Naomi”. (Cf. Rashi on that verse). Wherever the words איש and אישך occur they must be translated by בעל; so, too, (1 Kings 2:2) “Be thou strong and show thyself an איש” — a mighty person.

כלם אנשים, men of valour. The word איש occurs in the sense of “man of valour” both in Samuel I 26,15 and in Kings I 2,2.

כולם אנשים, “all of them distinguished people.” They were well known for their prowess. The word איש appears in that context in Kings I 2,2 וחזקת והיית לאיש.
