Isaiah now applied this knowledge of God to the discouraging prospect that the Judahites faced, namely: Babylonian captivity (cf. Isaiah 39:6). Even though Isaiah spoke to the nation from the perspective of the captivity being past, he still addressed his pre-exilic contemporaries. He encouraged them by pointing to the sufficiency of their God. Since the Creator knows the name of everything in His complex creation, how could Hebrews , the God of Israel, possibly forget His covenant people? Since He is as powerful as He Isaiah , how could He be incapable of helping them?[source]
