of valiant men, men able to bear buckler and sword, and to shoot with
bow, and skilful in war;
strong able bodied men; and not only able to bear and carry arms, sword in one hand, and shield in another; but were men of valour and courage, and had military skill, and knew how to handle their arms to advantage:

Divrey Hayamim Alef 5:18 In-Context

16 And they dwelt in Gil’ad in Bashan, and in her towns, and in all the migrashim (open lands) of Sharon, within their borders.

17 All these were reckoned by genealogies in the days of Yotam Melech Yehudah, and in the days of Yarov’am Melech Yisroel.

18 The Bnei Reuven, and the Gadi, and half the shevet (tribe) of Menasheh, of bnei chayil, anashim able to bear mogen and cherev, and to shoot with keshet, and trained for milchamah, were four and forty elef seven hundred and threescore, that were ready for military service.

19 And they waged milchamah against the Hagari’im, with Yetur, and Naphish, and Nodav.

20 And they were helped against them, and the Hagari’im were delivered into their yad, and all that were with them, for they cried to Elohim in the milchamah, and He was entreated of them [T.N. These genealogies establish the massively eyewitnessed veracity of the death and resurrection of Israel in and from the Golus.] because they put their trust in Him.
