CONSOLATION FOR THE PEOPLE OF GOD
SITUATION
The authorship of the later chapters of Isaiah is debated; the geographical and historical perspective of these chapters shifts from Jerusalem at the turn of the seventh century BC to Babylon in the mid-sixth century BC. As a prophet, Isaiah could have been shown circumstances and events 150 years in the future. But the tone of the speeches in this later section suggests they were written by a contemporary of the events, who pleads with the people to trust God for restoration.
Regardless of the setting and identity of the human author, these chapters have much in common with chs. 1–39. They show a well-planned development of Isaiah’s concerns for Yahweh’s holiness, sovereignty, and plans for restoration of Judah.
COMPLICATION
Failure to Move Forward
40:3–4 Preparing the Way of the King
A voice of one calling: “In the desert prepare the way for the LORD; make straight in the wilderness a highway for our God. Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain.
It’s been the custom for centuries for Eastern monarchs who are traveling through their domain to send men before them to prepare their way by removing stones (see Isaiah 62:10), leveling rough places, filling up hollows, cleaning up trash and litter, and generally making the road pleasant and easy for the distinguished travelers and their guests. One of the stories told about the semilegendary Queen Sammu-ramat (Semiramis of Greek legend, and mother of king Adad-nirari III, who reigned from 810 to 783), is that on one of her journeys she came to a rough, mountainous, region, and ordered the hills leveled and the hollows filled, which was done at enormous cost. Her object was not only to shorten her way, but to leave to posterity a lasting monument to herself. Since her time there have been other instances of similar character, but none involving so much labor and expense.
In Matthew 3:3, Mark 1:3, Luke 3:4, and John 1:23, this passage is applied to John the Baptist who, as a herald, preceded the Messiah to announce His coming and prepare the way for Him (see Malachi 3:1).
Faulty Faith in Flesh
40:6–8 The preacher’s word. 6 This introduces the prophet and his responsibility (the RSV reading, ‘and I said’, retains the Hebrew consonants and is well supported). All men (lit. ‘flesh’) echoes the impressive all mankind (‘flesh’) of v 5 but puts it in perspective in God’s overwhelming presence. 8 Without the great ending of v 8, the passage would have only the wistfulness of e.g. Jb. 14:1–12; but with it, it reaffirms Isaiah’s tireless preaching of faith (cf. e.g. 7:9; 31:3). Its full implications will emerge in 1 Pet. 1:23–25, where the word, in its final form as gospel, is no longer the mere contrast to our transience but the cure of it. Cf. 1 Jn. 2:17.
