Charles Ellicott Commentary 1 Samuel 17:22

"And David left his baggage in the hand of the keeper of the baggage, and ran to the army, and came and saluted his brethren." — 1 Samuel 17:22 (ASV)

And David left his carriage. —That is, his baggage. The word “carriage,” as signifying baggage, is used in the English Version in this archaic sense in Isaiah 10:28: At Michmash he has laid up his carriages; and in Acts 21:15: We took up our carriages.
