"One who takes care of a fig tree will enjoy its fruit." Why is the Torah compared to a fig tree? Every fruit has a part which is inedible: in the date, it is the stone; in grapes, it is the pips; in the pomegranate, it is the seeds -- only the fig is entirely suitable as food."
(Yalkut Shimoni, Yehoshua 1)
Rabbi Yochanan Ben Zakkai once said:
"If you have sapling in your hand, ready to plant, and the Messiah comes, plant the tree first and then go to greet him."
(Avoth D'Rabbi Nathan)
One day, Honi was walking along, and say an old man planting a carob tree. Honi knew that the old man would not live to see the fruits of his labor. He asked the man: "Why do you bother to plant a tree if you will never see it's fruits?" The man answered: "I will not see this tree full grown, but my children will and their children will. I plant this tree for them."
Rami Bar Yechezkel once came to Bnei Brak and saw goats grazing under a fig tree. Honey was dripping from the figs and milk from the goats - and they became intermingled. He said: "Behold, a land flowing with milk and honey!" (Talmud - Ketubot 111b)
Rabbi Tarfon compared the Jewish people to a pile of walnuts. If one walnut is removed, each and every nut in the pile is shaken and disturbed. So too, when a single Jew is in distress, every other Jew is shaken.
(Midrash - Shir HaShirim Raba 6:11)
And it came to pass at the end of forty days, that Noah opened the window of the ark which he had made;And he sent forth a raven, which went forth to and fro, until the waters were dried up from off the earth.Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;But the dove found no rest for the sole of its foot, and she returned to him into the ark, for the waters were on the face of the whole earth; then he put forth his hand, and took her, and pulled her into the ark.And he stayed yet other seven days; and again he sent forth the dove out of the ark;And the dove came in to him in the evening; and, lo, in her mouth was an olive leaf plucked off; so Noah knew that the waters were abated from off the earth.
(Genesis 8, 6-11)

(Mishnah – Rosh HaShana 1,1)
Let me tell you a parable — To what may this be compared? To a man who was journeying in the desert; he was hungry, weary and thirsty and he lighted upon a tree the fruits of which were sweet, its shade pleasant, and a stream of water flowing beneath it; he ate of its fruits, drank of the water, and rested under its shade. When he was about to continue his journey, he said: Tree, O Tree, with what shall I bless thee? Shall I say to thee, ‘May thy fruits be sweet’? They are sweet already; that thy shade be pleasant? It is already pleasant; that a stream of water may flow beneath thee? Lo, a stream of water flows already beneath thee; therefore [I say], ‘May it be [God's] will that all the shoots taken from thee.
(Talmud – Ta’anith 5b)
And when you shall come into the land, and shall have planted all kinds of trees for food, then you shall count its fruit as uncircumcised; three years shall it be uncircumcised to you; it shall not be eaten.But in the fourth year all its fruit shall be holy for praise giving to the Lord.And in the fifth year shall you eat of its fruit, that it may yield to you its produce; I am the Lord your God.
(Leviticus 19, 23-25)
