Interpretation

Isaiah 30:21 shows a direction that is lived within family life—see "when" and "turn". Choose direction in generosity without notice—let wisdom become a road.

Context

Isaiah speaks here as prophetic oracle writing, highlighting direction. Within ch. 30, a small unit frames the emphasis. It edges toward prophetic hope & judgment. Watch the terms “when” and “turn”.

Authorship & Historical Background

Long‑standing tradition credits Isaiah to Isaiah son of Amoz. Isaiah is frequently described this way: Many propose layered composition across exilic and post‑exilic periods.. Scholars commonly date Isaiah 8th–5th century BC. Prophetic Hope & Judgment is especially relevant in this line. Judgment and comfort are braided together. Chs 40–55 commonly exilic (Deutero). Chs 56–66 commonly post‑exilic (Trito). A long compositional arc is often proposed (Proto/Deutero/Trito).

Manuscripts & Textual Witnesses
The Great Isaiah Scroll from Qumran (1QIsaa) preserves this verse nearly identical to the Masoretic Text. The only variation is minor spelling differences that don't affect meaning. The directional language 'right' and 'left' appears consistently. The Septuagint translation supports the Hebrew. The phrase 'This is the way' shows no textual variation. This passage demonstrates the remarkable accuracy of Isaiah's transmission.
