Translation
And I hated all my toilsome toil in which I had toiled
Go to footnote numberunder the sun because
I must leave it to the man who will come after me.
Paraphrase
and I hated all my irksome work at which I had worked
here on earth because I do not get to enjoy it in a lasting fashion, rather I must leave it behind for the one who will come after me and fill my position.
Footnotes
1: “I toiled”
Solomon had not done the menial labor, but he had been very involved in planning and coordinating all the expansions and building projects that went on during the first two or three decades of his reign. I picture him being very involved in order to make sure things were done at the level of perfection he desired.
