Maybe I was wrong about what exactly the fig tree symbolizes, but I'm certain Israel is the Olive Tree. But don't take my word for it, take Yahweh God's.
THE OLIVE TREE
KJV Jeremiah 11:1-2, 16-17
1 The word that came to Jeremiah from the LORD, saying,
2 Hear ye the words of this covenant, and speak unto the men of Judah, and to the inhabitants of Jerusalem;
16 The LORD [Yahweh] called thy name, A green olive tree, fair, and of goodly fruit: with the noise of a great tumult he hath kindled fire upon it, and the branches of it are broken.
17 For the LORD [Yahweh] of hosts, that planted thee, hath pronounced evil against thee, for the evil of the house of Israel and of the house of Judah, which they have done against themselves to provoke me to anger in offering incense unto Baal.
Of course, Judah is included in the Olive Tree as it is part of Israel.
KJV Hosea 14:5-6
5 I will be as the dew unto Israel: he shall grow as the lily, and cast forth his roots as Lebanon.
6 His branches shall spread, and his beauty shall be as the olive tree, and his smell as Lebanon.
KJV Romans 11:24-25
24 For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own [color]olive tree[/color]?
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
THE FIG TREE
Matthew 21:18-22
18 Now in the morning as he returned into the city, he hungered.
19 And when he saw a fig tree in the way, he came to it, and found nothing thereon, but leaves only, and said unto it, Let no fruit grow on thee henceforward for ever. And presently the fig tree withered away.
20 And when the disciples saw it, they marvelled, saying, How soon is the fig tree withered away!
21 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
22 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
Mark 11:11-22
11 And Jesus entered into Jerusalem, and into the temple: and when he had looked round about upon all things, and now the eventide was come, he went out unto Bethany with the twelve.
12 And on the morrow, when they were come from Bethany, he was hungry:
13 And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon: and when he came to it, he found nothing but leaves; for the time of figs was not yet.
14 And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever[/u[. And his disciples heard it.
15 And they come to Jerusalem: and Jesus went into the temple, and began to cast out them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves;
16 And would not suffer that any man should carry any vessel through the temple.
17 And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves.
18 And the scribes and chief priests heard it, and sought how they might destroy him: for they feared him, because all the people was astonished at his doctrine.
19 And when even was come, he went out of the city.
20 And in the morning, as they passed by, they saw the fig tree dried up from the roots.
21 And Peter calling to remembrance saith unto him, Master, behold, the fig tree which thou cursedst is withered away.
22 And Jesus answering saith unto them, Have faith in God.
Matthew 24:32-33
32 Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:
33 So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
Mark 13:28-29
28 Now learn a parable of the fig tree;When her branch is yet tender, and putteth forth leaves, ye know that summer is near:
29 So ye in like manner, when ye shall see these things come to pass, know that it is nigh, even at the doors.
Luke 21:29-31
29 And he spake to them a parable; Behold the fig tree, and all the trees;
30 When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
Figs
Jeremiah 24:1-10
1 The LORD [Yahweh] shewed me, and, behold, two baskets of figs were set before the temple of the LORD [Yahweh], after that Nebuchadrezzar king of Babylon had carried away captive Jeconiah the son of Jehoiakim king of Judah, and the princes of Judah, with the carpenters and smiths, from Jerusalem, and had brought them to Babylon.
2 One basket had very good figs, even like the figs that are first ripe: and the other basket had very naughty figs, which could not be eaten, they were so bad.
3 Then said the LORD [Yahweh] unto me, What seest thou, Jeremiah? And I said,Figs; the good figs, very good; and the evil, very evil, that cannot be eaten, they are so evil.
4 Again the word of the LORD [Yahweh] came unto me, saying,
5 Thus saith the LORD [Yahweh], the God of Israel; Like these good figs, so will I acknowledge them that are carried away captive of Judah, whom I have sent out of this place into the land of the Chaldeans for their good.
6 For I will set mine eyes upon them for good, and I will bring them again to this land: and I will build them, and not pull them down; and I will plant them, and not pluck them up.
7 And I will give them an heart to know me, that I am the LORD [Yahweh]: and they shall be my people, and I will be their God: for they shall return unto me with their whole heart.
8 And as the evil figs, which cannot be eaten, they are so evil; surely thus saith the LORD [Yahweh], So will I give Zedekiah the king of Judah, and his princes, and the residue of Jerusalem, that remain in this land, and them that dwell in the land of Egypt:
9 And I will deliver them to be removed into all the kingdoms of the earth for their hurt, to be a reproach and a proverb, a taunt and a curse, in all places whither I shall drive them.
10 And I will send the sword, the famine, and the pestilence, among them, till they be consumed from off the land that I gave unto them and to their fathers.
KJV Isaiah 34:4
4 And all the host of heaven shall be dissolved, and the heavens shall be rolled together as a scroll: and all their host shall fall down, as the leaf falleth off from the vine, and as a falling fig from the fig tree.
KJV Hosea 9:10 I found Israel like grapes in the wilderness; I saw your fathers as the firstripe in the fig tree at her first time: but they went to Baalpeor, and separated themselves unto that shame; and their abominations were according as they loved.
This is the only verse which possibly refers to Israel as a fig tree. But notice that Yahweh God never explicily calls Israel the fig tree as He calls her the Olive Tree in Jeremiah 11 and Hosea 14,
KJV Luke 13:6-9
6 He spake also this parable; a certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none.
7 Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why cumbereth it the ground?
8 And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it:
9 And if it bear fruit, well: and if not, then after that thou shalt cut it down.
KJV John 1:47-48
47 Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!
48 Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee.
KJV James 3:12 Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
KJV Revelation 6:12-17
12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand?
