I the Preacher was king over Israel in Jerusalem. I the Preacher was king - This is a strange verse, and does not admit of an easy solution. It is literally, "I, Choheleth, have been king over Israel, in Jerusalem." This book, as we have already seen, has been conjectured by some to have been written about the time that Ptolemy Philadelphus formed his great library at Alexandria, about two hundred and eighty-five years before our Lard; and from the multitude of Jews that dwelt there, and resorted to that city for the sake of commerce, it was said there was an Israel in Alexandria. See the introduction.
It has also been conjectured from this, that if the book were written by Solomon, it was intended to be a posthumous publication. "I that was king, still continue to preach and instruct you." Those who suppose the book to have been written after Solomon's fall, think that he speaks thus through humility. "I was once worthy of the name of king: but I fell into all evil; and, though recovered, I am no longer worthy of the name." I am afraid this is not solid.
