Commentators note two main interpretations of this phrase. One view, mentioned by John Gill, is that these men were later promoted by David to become commanders over units of 100 and 1000. A second view, supported by the poetic language and links to Leviticus 26:8, is that it describes their incredible fighting prowess—the weakest could defeat 100 enemies and the strongest could defeat 1000. Both views emphasize their exceptional skill and value.
