1 Samuel 25:4 - Ellicott's Commentary On The Whole Bible

And David heard in the wilderness. — The question of the support of the large band of devoted followers who obeyed David must have been usually a very anxious one. No doubt, contributions from the farmers and sheep-masters materially aided the supplies David and his men derived from their raids across the Philistine borders. It is likely enough that some of these contributions were not always willingly made; still, there is no doubt that the presence of the armed band of David during the latter years of Saul afforded considerable protection to the border land. His position resembled that of a modern Arab sheik of a friendly Bedaween tribe, and it is clear that on the whole his career as head of an army of free lances tended to popularise him among the southern tribes of Israel. Nabal’s conduct appears to have been more than churlish and foolish, for David, according to the showing of Nabal’s own shepherds, had on many occasions been of substantial service to them as they tended their flocks in exposed and dangerous localities. The testimony of these shepherd folk may be accepted generally as the popular estimate of David and his acts during this rough and sorely tried period of his life.
