The Fig Tree

Whoso keepeth the fig tree shall eat the fruit thereof
Proverbs 27:18

Why was the Torah likened to a fig tree? Because, while the fruit of most other trees – the olive tree, the vine, and the date tree – is gathered all at once, that of the fig tree is gathered little by little; and it is the same with the Torah. One gathers a little learning today and much tomorrow, for it cannot be learned in a year nor in two years. Midrash Rabbah Numbers 21:15
