John Gill Commentary 1 Samuel 30:19

"And there was nothing lacking to them, neither small nor great, neither sons nor daughters, neither spoil, nor anything that they had taken to them: David brought back all." — 1 Samuel 30:19 (ASV)

And there was nothing lacking to them, neither small nor great, neither sons nor daughters Not any of the least or youngest, nor any of them that were grown up; for as these were not slain but carried captive, so they were brought back, and not one missing, see (1 Samuel 30:2);

neither spoil, nor any [thing] they had taken to them : except the food they had eaten and the liquor they had drank, as before observed; and perhaps what they had ate and drank were none of theirs, but the Philistines: so that

David recovered all ; taken in the utmost extent.
