1 Samuel 25:7

Neither was there ought missing unto them. — These words doubtless refer to the protection which David’s armed band had afforded to the herdsmen against the frequent raids of the neighbouring people — the Philistines and other more savage and unscrupulous tribes who dwelt on the borders of Palestine. The request was certainly a fair one, for, as Lange and Ewald remark, “apart from the Eastern custom of giving largely at such great merry-makings, according to which such a request would seem in no way strange, David had a certain right to ask a gift from Nabal’s wealth. He had indirectly no small share in the festal joy of Nabal and his house. Without some part of the superfluity of the inhabitants whom he protected, he could not have maintained himself and his army.”
