ידע הוא כוח

for God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as God, knowing good and evil.’

Elisha ben Abuyah said: He who learns when a child, to what is he compared? To ink written upon a new writing sheet. And he who learns when an old man, to what is he compared? To ink written on a rubbed writing sheet. Rabbi Yose ben Judah a man of Kfar Ha-babli said: He who learns from the young, to what is he compared? To one who eats unripe grapes, and drinks wine from his vat; And he who learns from the old, to what is he compared? To one who eats ripe grapes, and drinks old wine. Rabbi said: don’t look at the container but at that which is in it: there is a new container full of old wine, and an old [container] in which there is not even new [wine].
