John Gill Commentary 2 Samuel 16:1

"And when David was a little past the top [of the ascent], behold, Ziba the servant of Mephibosheth met him, with a couple of asses saddled, and upon them two hundred loaves of bread, and a hundred clusters of raisins, and a hundred of summer fruits, and a bottle of wine." — 2 Samuel 16:1 (ASV)

And when David was a little past the top [of the hill]
Of the mount of Olives, the ascent of which he is said to go up by, and to come to the top of it, (2 Samuel 15:30 2 Samuel 15:32) ;

behold, Ziba, the servant of Mephibosheth, met him ;
of whom see (2 Samuel 9:2) ;

with a couple of asses saddled :
and so fit to ride on, but for the present he used them to another purpose:

and upon them two hundred [loaves] of bread ;
an hundred on each ass very probably:

and an hundred bunches of raisins ;
or dried grapes, as the Targum: and an hundred of summer fruits :
not in number, but in weight, as apples, pears, plums, apricots so the Targum, an hundred pounds of figs: and a bottle of wine :
a cask or flagon of wine; for a bottle, such as is in use with us, would have signified nothing in such a company.
