What does 2 Samuel 16:2 mean?

The king asked Ziba, 'Why did you bring all this?' Ziba answered, 'The donkeys are for your family to ride, the bread and fruit are for your people to eat, and the wine is for anyone who gets tired in the wilderness.' 2 Samuel 16:2 - Modern Text Bible

(David asks about the supplies, and Ziba explains they're meant to help David and his followers survive while they're on the run.)
