Honi and the carob tree
Taanit 23a:14-15 · Sefaria Community Translation
אָמַר רַבִּי יוֹחָנָן: כׇּל יָמָיו שֶׁל אוֹתוֹ צַדִּיק, הָיָה מִצְטַעֵר עַל מִקְרָא זֶה: ״שִׁיר הַמַּעֲלוֹת בְּשׁוּב ה׳ אֶת שִׁיבַת צִיּוֹן הָיִינוּ כְּחֹלְמִים״, אָמַר: מִי אִיכָּא דְּנָיֵים שִׁבְעִין שְׁנִין בְּחֶלְמָא?
Said Rabbi Yochanan, "All the days of that righteous one, he was troubled about this verse (Psalme 126:1), 'A Song of Ascents: With the Lord's return of the captivity of Zion, we will be like dreamers.' He said, 'Is there someone who can fall asleep for seventy years in a dream?'
יוֹמָא חַד הֲוָה אָזֵל בְּאוֹרְחָא, חַזְיֵיהּ לְהָהוּא גַּבְרָא דַּהֲוָה נָטַע חָרוּבָא, אֲמַר לֵיהּ: הַאי, עַד כַּמָּה שְׁנִין טָעֵין? אֲמַר לֵיהּ: עַד שִׁבְעִין שְׁנִין. אֲמַר לֵיהּ: פְּשִׁיטָא לָךְ דְּחָיֵית שִׁבְעִין שְׁנִין? אֲמַר לֵיהּ: אֲנָא חָרוּבָא בְּעָלְמָא אַשְׁכְּחֵיהּ. כִּי הֵיכִי דִּשְׁתַלוּ לִי אֲבָהָתִי — שְׁתַלִי נָמֵי לִבְרָאִי.
One day, he was walking on the road and saw a certain man that was planting a carob tree. He said to him, 'How many years until this [tree] will be laden [with fruit]?' He said to him, 'Until seventy years.' He said to him, 'Is it obvious to you that you will live [another] seventy years?' He said to him, 'That man found the world with carob trees. In the same way as my fathers planted for me, I will also plant for my children.'
