There is some question as to whether verse 6 more properly belongs as part of the poem in 26:7ff or with what follows in 27:7-13. The scribe of the great Qumran Isaiah scroll (1QIsaa) left a space after verse 5, which indicates that he felt verse 6 started a new section. In my view is seems better to consider it as the closing refrain of the poem in 26:7-27:6. After the two “Day of YHWH” stanzas (see the prior notes on v. 1 and vv. 2-5), we have this final declaration of what will take place for Israel in the coming days.
“(In) the coming (day)s,
He will cause Ya’aqob to take root,
He will make Yisrael blossom and sprout,
and they will fill the face of the t¢»¢l (with) fruit.”
This climactic stanza is a declaration of the restoration of God’s people in the Age to Come. The restoration of Israel (and return from exile) was a frequent theme in the 7th and 6th century Prophets, and one which gradually took on an eschatological significance. That is to say, Israel’s restoration/return would mark the beginning of a New Age for God’s people, coinciding with the end of the current Age. The end of the Age is the time of the great Judgment (the “Day of YHWH”) against the nations and the wicked on earth. This eschatological orientation is found throughout most of chapters 24-27, and is one of the reasons the section is commonly referred to as the Isaian “Apocalypse”. Later Jewish and early Christian apocalyptic literature (such as the book of Revelation) was greatly influenced by these chapters.
In our discussion of the vineyard poem in vv. 2-5 (see the previous note in this set), we saw how the severe announcement of judgment in the earlier poem of 5:1-7 was softened considerably in chap. 27, expressed more in terms of a message of hope for God’s people. The sense of warning remained, but framed as an exhortation for Israel to remain faithful to God, in the face of the coming judgment on all the nations of the earth.
The horticultural imagery of the vineyard poem continues in this final stanza, predicting the future fruitfulness of Israel and Judah. In the Age to Come (“[the] coming [days]”), YHWH will act out anew his role as owner of the vineyard, planting and caring for it. Now, however, instead of it producing rotten grapes or thorn bushes (in whole or part), there will be growth so prodigious, and fruit so complete, that it will cover the surface of the earth. The noun t¢»¢l (lb@T@), left untranslated above, is a tricky word to render precisely in English. It generally signifies the surface of the earth or land, along with what is contained in it. Sometimes this refers to the people who live and move about on the land—the earth and its inhabitants, i.e. the inhabited world—other times to natural and geographic features. Implicit in the noun, with its derivation from a root meaning “bring, carry, bear”, is the idea of the fertile parts of the earth—i.e. those which bring forth and produce fruit. These are also the parts of the land where human beings are likely to set up communities, and where populations will grow. Thus the word t¢»¢l is essential to the overall agricultural imagery of the stanza, a fact that is almost completely obscured when translating it simply as “world” or “earth”.
The fruitfulness of Israel here relates to the common 6th century prophetic theme that the restoration of God’s people will involve a complete transformation of heart and mind—i.e. a new heart and a new spirit—brought about entirely by the action of God’s own Spirit. It is no longer a question of whether or not Israel will choose to be faithful to the covenant; the presence and work of God’s Spirit will ensure that His people remain faithful, holy and pure, now and into the distant future. This important emphasis represents the development of a more general motif—of God “pouring” his Spirit upon the land (and its people) as a whole (see Isa 32:15; 44:3, and my earlier note on these verses). The connection of this agricultural imagery with our passage here in vv. 2-6 is certainly clear enough.
