Take a harp, Go about the city, Thou harlot long forgotten; Make sweet melody, Sing many songs, That thou mayest be remembered.
Rashi on Isaiah
sing many songs That is to say, also make many supplications and humble your haughtiness.
Ibn Ezra on Isaiah
Take up an harp, etc. The forgotten harlot walks about the city playing, that she may be remembered again; thus Tyre will send letters to all her neighbours, that the merchants may again come to her as before.
