The Hebrew name Solomon has a “sh” sound at the beginning—it is “shelomoh.” The bride of the story is identified not by her name but by a title—she is “the Shulamite” (6:13), which is another form of the same root word. We might speak of the Shulamite then as “the Solomoness.” Both these words “Solomon” and “Shulamite” come from one root word—Shalom, meaning safe, welfare, or peace.
David was Israel’s poet laureate, not Solomon (2 Samuel 23:1). For all of David’s inscripturated songs, it was Solomon who was divinely inspired to write this superlative song—the “Song of Songs”—perhaps for the same reason that Solomon was chosen to build the temple; David was a man of war (1 Chronicles 22:8-9).
Of these two kings, David was the warring conquering king, a man of blood. Solomon reigned over the peace that his father had won. Both these kings of course, point to the King of kings who has conquered our enemy and has brought peace for us through the blood of his cross (Colossians 1:20).
Our Bridegroom is the Conqueror (Revelation 6:2), and therefore the “Prince of Peace” (Isaiah 9:6).
