John Trapp on Isaiah 2:20

Ver. 20. In that day a man ſhall caſt his Idols] Though never ſo much worth either for weight or workmanſhip, for value or elegancy: he ſhall pollute what before he had perfumed, Iſa. 30.22.

To the Moles and to the Bats] Coeci coeca coecis, having their eyes opened in that extream danger: as the Mole hath they ſay, when the pangs of death are upon her. Theſe aſhamed of their vain confidences, and haſting to hide themſelves, ſhall caſt their Idols into by-corners, ſaying as chap. 30.22. Get you hence. Moles do all their miſchief by working under ground; ſo ſaith Epiphanius do Hereticks: but if once they be above ground, they are weak and contemptible creatures. Bats have wings as a Bird, and teeth as a Beaſt: being both, and yet neither. Such are our Veſpertilian Profeſſors, time-ſerving Goſpellers, who ſhould do well to caſt away either their wings or their teeth: and loathing this bat like Nature, be what they are, either birds or beaſts.
