גַּ֣ם מִגָּבֹ֤הַּ יִרָ֙אוּ֙ וְחַתְחַתִּ֣ים בַּדֶּ֔רֶךְ וְיָנֵ֤אץ הַשָּׁקֵד֙ וְיִסְתַּבֵּ֣ל הֶֽחָגָ֔ב וְתָפֵ֖ר הָֽאֲבִיּוֹנָ֑ה כִּֽי־הֹלֵ֤ךְ הָאָדָם֙ אֶל־בֵּ֣ית עוֹלָמ֔וֹ וְסָבְב֥וּ בָשּׁ֖וּק הַסֹּפְדִֽים׃
como também quando temerem o que é alto, e houver espantos no caminho; e florescer a amendoeira, e o gafanhoto for um peso, e falhar o desejo; porque o homem se vai à sua casa eterna, e os pranteadores andarão rodeando pela praça;
Shemirat HaLashon
As to Solomon's using the word "vineyard," aside from the fact that all of Israel is considered a vineyard, viz. (Isaiah 5:7): "For the vineyard of the L-rd of hosts is the house of Israel," and every Jew has a portion in this vineyard— aside from this, everyone has a distinct vineyard in Gan Eden, as it is written (Koheleth 12:5): "A man goes to his eternal house." And he must take especial care with it, to plant it with pleasing growths and to guard it that it not spoil.
