1Ch 12:21
These helped David הגּדוּד על, against the detachment of Amalekites, who during David’s absence had surprised and burnt Ziklag, and led captive the women and children (1Sa 30:1-10). This interpretation, which Rashi also has (contra turmam Amalekitarum), and which the Vulgate hints at in its adversus latrunculos, rests upon the fact that in 1Sa 30:8, 1Sa 30:15, the word הגּדוּד, which in general only denotes single detachments or predatory bands, is used of the Amalekite band; whence the word can only refer to the march of David against the Amalekites, of which we have an account in 1Sa 30:9., and not to the combats which he had with Saul. “For they were all valiant heroes, and were שׂרים, captains in the army,” sc. which gathered round David.
