This paper seeks to consider how Yahweh's sovereignty is highlighted in Isaiah 1-66. For this purpose, the Isaiah Book was divided into three parts and examined the period background of each part and the texts of presenting a vision for the future, and gôi or the expressions associated with the gôi.
Isaiah 1-66 contains three different periodical backgrounds (8th century BCE, ch. 1–39; Babylon exilic period, ch. 40–55; the post exilic period, ch. 56–66), but focuses in common on Yahweh's sovereignty. In the three parts above, Yahweh's sovereignty is described and emphasized through historical crisis situations, future expressions, and gôi or the expressions related to gôi. In short, each prophecy refers to Yahweh's sovereignty, describing the current historical crisis situation and the presentation of the vision of the future, and adding expressions related to gôi to expand Yahweh as the sovereign of the universe.
Isaiah 1-39 emphasizes the importance of Yahweh's trust in the situation of the Syrian-Ephraim War and the invasion of Sennacherib, saying that the nations and all Israel will recognize Yahweh's sovereignty over the world and return to give him gifts. Isaiah 40-55 insists that God's people had not been taken prisoner by the defeat of Marduk, and emphasizes Yahweh's cosmic sovereignty through four concepts related to Yahweh's identity (the only God, creator, savior, the Lord of history) and the "new work" related to the salvation of foreigners and escape from Babylon. Isaiah 56–66 emphasizes Yahweh's sovereignty in connection with the issue of delay in salvation and the acceptance of foreigners in the post-exilic period. In particular, it is emphasized that the delay in salvation did not result from Yahweh's incompetence and indifference, but because of the sins of the people, and that even foreigners can be saved if they obey Yahweh. In addition to the complete recovery of Zion, Yahweh strengthens his cosmic sovereignty through the presentation of the new heavens and the new earth the salvation of the foreigns will be completed.
This argument will be one of the good alternatives to an integrated understanding of the three-part in the book of Isaiah.
