Rabbi Yehoshua ben Levi interpreted the verse regarding Israel upon their entry into the land. “I increased my actions [maasai]” (Ecclesiastes 2:4) – “When you will come to the land of your dwellings.… you will perform [vaasitem] a fire offering to the Lord” (Numbers 15:2–3). “I built myself houses” (Ecclesiastes 2:4) – “houses filled with everything good” (Deuteronomy 6:11). “I planted myself vineyards” (Ecclesiastes 2:4) – “vineyards and olive trees that you did not plant” (Deuteronomy 6:11). “I made myself gardens and orchards” (Ecclesiastes 2:5) – Hadrian, may his bones be crushed, asked Rabbi Yehoshua ben Ḥananya: ‘It is written in the Torah: “A land in which without poverty [you will eat bread; you will not lack anything there]” (Deuteronomy 8:9). Can you bring me three things that I request?’ He said to him: ‘What are they?’ He said to him: ‘Peppers, pheasants, and silk fabrics.’ [Rabbi Yehoshua ben Ḥananya] brought him peppers from Nitzḥana, pheasants from Tzaidan, and some say from Akhberin, and silk fabric from Gush Ḥalav. “I made myself pools of water” (Ecclesiastes 2:6) – as it is written: “A land of streams of water” (Deuteronomy 8:7). “To irrigate from them a forest which grows trees” (Ecclesiastes 2:6) – even wood for the shafts of arrows was not lacking in the Land of Israel.
“I purchased myself slaves and maidservants” (Ecclesiastes 2:7) – “a mixed multitude [left with them]” (Exodus 12:38). “And I had stewards” (Ecclesiastes 2:7) – these are the Givonites, whom Joshua tasked as hewers of wood and drawers of water, as it is stated: “Joshua made them that day hewers of wood and drawers of water” (Joshua 9:27). “I also had great possession of herds and flocks” (Ecclesiastes 2:7) – “[the children of Gad and the children of Reuben had a very great] multitude of livestock…” (Numbers 32:1). “I also gathered for myself silver and gold” – these are matters of Torah, as it is stated: “He took them out with silver and gold” (Psalms 105:37). “And the treasure of kings and countries” – these are the spoils of Og and the spoils of Midyan.²⁵See Numbers 21:35 and 31:9. “I acquired for myself songsters and songstresses” – male singers and women singers. “And the pleasures of people” – these are the pleasures of the children of Israel; “chests [shidda] and wagons [shiddot]” – indulgences and luxuries.

... R’ Shimon bar Aba said in the name of R’ Yochanan: any where that it says ‘and it was’ (vayehi) it indicates distress and joy. If it is distress there is no distress like it and if it is joy there is no joy like it. R’ Shmuel ben Nachmani came and split the teaching in half. Anywhere that it says ‘and it was’ (vayehi) indicates distress, ‘and it will be’ (v’haya) indicates joy…The brought a challenge from this verse “…and he was [there] (v’haya) when Jerusalem was taken.” (Jeremiah 38:28) He said to them: this is still a cause of joy because on that very day Israel received full payment for their sins. As R’ Shmuel ben Nachmani said: Israel received full payment for their sins on the day the Holy Temple was destroyed, as it says “Your iniquity is finished, O daughter of Zion…” (Lamentations 4:22)
