The fig tree in ancient Palestine was the most important of all trees.
In a warm climate, like that of Palestine, it was fruitful during much of the year. Its so-called "immature figs" began to appear in April; then followed the two main crops, the early one in June and the later one in August.
The fig tee was valued for other reasons. Although it was not a large tree, ranging on an average from ten to fifteen feet high, its foliage was remarkably dense, well-suited for a cool shade from the summer heat.
The fig tree was recognized as a symbol of peace and prosperity. In the time of Solomon it is said that "Judah and Israel dwelt in safety, from Dan even to Beer-sheba, every man under his vine, and under his fig tree." Thus the fig tree was an invaluable tree and was cultivated all over the land of Palestine.
