The title says that the Song we are about to read is “of Solomon.” The Hebrew allows this phrase to be understood in several ways. It could mean that King Solomon is the author of the Song, the subject of the Song, or that the Song is somehow influenced by him. It could even be a combination of these possibilities. It seems unlikely that Solomon wrote the Song because the things that are held up as excellent in the Song do not match the harsh realities of Solomon’s life, with his three hundred wives and seven hundred concubines, as recorded in 1 Kings. It is very likely, therefore, that the Song was written by someone other than Solomon and we do not know who the author is. But the Song was written during his reign as king of Israel (971-931 BC) and so the reign of Solomon has an influence on the contents of the Song.
