Shared ground
The passage presents an intentional, ongoing “watch” over Jerusalem: the speaker says watchmen are placed on the city’s walls, and their defining feature is that they are not “day nor night.” The text then identifies these watchmen as people who “call on Yahweh,” so their watch includes direct address to God, not only observing the city.
A second clear feature is persistence. The watchmen are told both “take no rest” and “give him no rest.” Whatever the precise form of their activity, the point is sustained, repeated urging rather than a single moment.
Finally, the passage sets a clear goal and endpoint: their persistence continues “until” Yahweh establishes Jerusalem and makes Jerusalem “a praise in the earth.” The outcome is public and recognizable, not merely private reassurance.
Where interpretation differs
Who the watchmen are. Some read the watchmen as human figures within Israel’s life (for example, prophetic voices or leaders) appointed to keep speaking and praying for Jerusalem’s restoration. Others read them more symbolically, as a poetic way to describe an unending chorus of intercession around Zion, without specifying an office or group.
What “give him no rest” refers to. Many read it primarily as prayer language—pressing God with requests. Others think it can also include public proclamation: watchmen who “won’t be silent” may be continually announcing Zion’s coming renewal while also calling on Yahweh.
What it means for Jerusalem to be “established” and “a praise in the earth.” Some take this mainly as restored security and stable communal life in Jerusalem after crisis. Others emphasize Jerusalem’s reputation among the nations—its renewed honor and visibility as evidence of Yahweh’s work.
Why the disagreement exists
The imagery blends two roles often associated with watchmen: alert public speech from the walls (“not silent”) and direct address to God (“call on Yahweh”). Because the text holds both together and does not name the watchmen (prophets, priests, etc.), readers differ on whether the primary stress is intercession, proclamation, or both. Likewise, the phrases “establish Jerusalem” and “a praise in the earth” are broad enough to include security, governance, worship life, and international reputation.
What this passage clearly contributes
Explicitly, it links Jerusalem’s promised renewal with continuous, organized calling on Yahweh. It portrays persistence as part of the story of restoration: the watchmen keep at it “until” Yahweh’s promised public outcome arrives. The passage also frames Jerusalem’s renewal as something meant to be widely seen and affirmed (“a praise in the earth”), not only enjoyed internally. Isaiah 62:6–62:7 therefore contributes a picture of restoration that is both God-driven (“until he establish”) and marked by sustained human speech toward God and outwardly about Zion.
