And the Master (Lord) answered and said unto me: Understandest thou not that the fig-tree is the house of Israel? Even as a man that planted a fig-tree in his garden, and it brought forth no fruit. And he sought the fruit thereof many years and when he found it not, he said to the keeper of his garden: Root up this fig-tree that it make not our ground to be unfruitful. And the gardener said unto God: (Suffer us) to rid it of weeds and dig the ground round about it and water it. If then it bear not fruit, we will straightway remove its roots out of the garden and plant another in place of it. Hast thou not understood that the fig-tree is the house of Israel? Verily I say unto thee, when the twigs thereof have sprouted forth in the last days, then shall feigned Christs come and awake expectation saying: I am the Christ, that am now come into the world. And when they (Israel) shall perceive the wickedness of their deeds they shall turn away after them and deny him [whom our fathers did praise], even the first Christ whom they crucified and therein sinned a great sin. But this deceiver is not the Christ. [Something is wrong here – the sense required is that Israel perceives the wickedness of antichrist and does not follow him.] And when they reject him he shall slay with the sword, and there shall be many martyrs. Then shall the twigs of the fig-tree, that is, the house of Israel, shoot forth: many shall become martyrs at his hand. Enoch and Elias shall be sent to teach them that this is the deceiver which must come into the world and do signs and wonders to deceive. And therefore shall they that die by his hand be martyrs, and shall be reckoned among the good and righteous martyrs who have pleased God in their life. Apocalypse of Peter: The Ethiopic Text
Let not the Kingdom of Heaven wither away. For it is like a date palm shoot whose fruits poured down around it. It put forth leaves and, when they budded, they caused the productivity of the date palm to dry up. Thus it is also with the fruit which came from this single root; when the fruit was picked, fruits were collected by many harvesters. It would indeed be good if it were possible to produce these new plants now; for then you would find the Kingdom. The Secret Book of James
Become zealous about the Word. For the Word’s first condition is faith; the second is love; the third is works. Now from these comes life. For the Word is like a grain of wheat. When someone sowed it, he believed in it; and when it sprouted, he loved it, because he looked forward to many grains in the place of one; and when he worked it, he was saved, because he prepared it for food. Again he left some grains to sow. Thus it is also possible for you all to receive the Kingdom of Heaven: unless you receive it through knowledge, you will not be able to find it. ibid.
When we heard these things, we became distressed. Now when he saw that we were distressed, he said: 'This is why I say this to you, that you may know yourselves. For the Kingdom of Heaven is like an ear of grain which sprouted in a field. And when it ripened, it scattered its fruit and, in turn, filled the field with ears of grain for another year. You also: be zealous to reap for yourselves an ear of life, in order that you may be filled with the Kingdom. ibid.
