Take a harp, go about the city,.... As harlots used to do, that by their music, both vocal and instrumental, they might allure men into their company to commit fornication with them; so Tyre is directed to, or rather this is a prophecy that she should take very artful and ensnaring methods to restore her commerce and merchandise:thou harlot that hast been forgotten; See Gill on "Isa 23:15":make sweet melody; or, "do well by striking" ; that is, the harp in her hand; strike it well with art and skill, so as to make melody, and give pleasure:sing many songs; or, "multiply a song" ; sing one after another, till the point is carried aimed at:that thou mayest be remembered; men may took at thee again, and trade with thee as formerly, who had been so long forgotten and neglected.
