After the flood, Noah broke fresh ground for a vineyard. He had tasted the grape and prized it twice — for its fruit and for its juice.
As he worked, Ha-Satan — the heavenly Accuser, who in Jewish tradition works as a tester of human character — came walking through the new world. He asked what Noah was planting. Noah told him: vines, for the pleasure of wine.
"Let me help you," Ha-Satan said.
He went off and returned with four animals: a lamb, a lion, a pig, and a monkey. He slaughtered each at the roots of the young vines and fed their blood into the soil as fertilizer.
When the work was done, he stepped back and explained the arithmetic of his gift. "Of those who drink the juice of these grapes," he said, "some will turn meek and gentle as the lamb. Some will grow bold and fearless as the lion. Some will become foul and beastly as the pig. And some will grow frolicsome and senseless as the monkey."
The four stages of any drinker — sweetness, courage, ugliness, foolishness — were planted in the soil that first afternoon.
The teaching is preserved in Midrash Tanchuma on Noach and in Yalkut Shimoni on Genesis. Ha-Satan did not poison the vine. He only named what it does.
