Isaiah 30:20-21

After God hid Himself from His people, having given them privation and oppression as their daily food and drink, as a prison sentence, He would finally reveal Himself to them again. As their teacher, God would guide them in His moral will (cf. Isaiah 30:15; Isaiah 26:9; Isaiah 28:9-13; Isaiah 29:11-12). Then their eyes would see Him and their ears would hear His voice correcting their deviations from His path (cf. Isaiah 30:9-11).
