The book of Isaiah, one of the prophetic books found in the Old Testament, is a literary masterpiece that presents a compelling and comprehensive picture of God’s perfect plan to use His people to bring the nations to Himself in worship. Isaiah’s contemporary ministry to God’s people occurred during the reigns of four kings of Judah (ca. 740–695 B.C., chapters 1–39). But he also prophesied to God’s people in two other specific periods as well: the period of the Babylonian exile (ca. 586–539 B.C., chapters 40–55) and a period of time after the remnant returned to Jerusalem from exile (ca. 540–440 B.C., chapters 56–66).

The Pentateuch is the first 5 books of the Old Testament, dealing with the creation of the universe and humankind as well as the plan of God’s restoration of humans after their rebellion (Genesis), the deliverance of Israel out of Egypt as well as the place where people could meet with God (Exodus), God’s laws for living among pagan ancient Near Eastern neighbors (Leviticus), the guidance and patience of God despite human disobedience (Numbers), and the preaching and application of God’s Law to his people poised to enter the Promised Land (Deuteronomy).
