1 Samuel 30:12

And they gave him a piece of cake of figs
That were dried and pressed together, and made into cakes:

and two clusters of raisins;
or dried grapes, as the Targum:

and when he had eaten, his spirit came again to him;
he seemed to be quite dispirited, almost lifeless, but upon eating some food he was refreshed, and his spirits revived, and he was capable of conversing:

for he had eaten no bread, nor drank [any] water, three days and three
nights;
that is, one whole day, and part of two days, as appears from ( 1 Samuel 30:13 ) .
