Bible
Raisins revive the Egyptian, so he can help David recover Ziklag's wives and people
A dying Egyptian servant to an Amalekite raider betrayed the band's position to David, and he was able to recover his wives and all the people of Ziklag and all the things stolen and more, the herds of the band. The Egyptian was left behind when he fell sick and had not eaten or had water in 3 days or nights, so David's bread, water, piece of cake of figs, and two clusters of raisins revived his spirit. (1 Samuel 30)
Ziba brings a gift as David fled Absalom
Ziba the servant of Mephibosheth met David as he passed beyond the summit with a gift of donkeys, 200 loaves of bread, 100 bunches of raisins, 100 summer fruits, and a skin of wine. The donkeys were for the king's household to ride on. (2 Samuel 16:1-4)
The Shulammite is sustained by raisins in the banqueting house
The Shulammite's beloved brings her to the banqueting house, and his banner over her is love. She asks him to sustain her with raisins, refresh her with apples, for she is sick with love. (Song of Solomon 2:3-4)
Cakes of raisins are used in false worship
And the Lord said to me, "Go again, love a woman who is loved by another man and is an adulteress, even as the Lord loves the children of Israel, though they turn to other gods and love cakes of raisins." (Hosea 3:1)
