Targum zu Kohelet 1:2

When Solomon the King of Israel foresaw, by the spirit of prophecy, the kingdom of Rehoboam his son, which will be divided with Jeroboam the son of Nebat, and that Jerusalem and the holy temple will be destroyed, and that the people of Israel will be led into captivity, he said by the divine word, Vanity of vanities is this world! Vanity of vanities is all which I and my father David have laboured for, all of it is vanity!
