Passage
All the people will know, including Ephraim and the inhabitants of Samaria, who say in pride and in arrogance of heart,
All the people will know, including Ephraim and the inhabitants of Samaria, who say in pride and in arrogance of heart,
Isaiah 9:7 Of the increase of his government and of peace there shall be no end, on David’s throne, and on his kingdom, to establish it, and to uphold it with justice and with righteousness from that time on, even forever. The zeal of Yahweh of Armies will perform this.
Isaiah 9:8 The Lord sent a word into Jacob, and it falls on Israel.
Isaiah 9:9 All the people will know, including Ephraim and the inhabitants of Samaria, who say in pride and in arrogance of heart,
Isaiah 9:10 “The bricks have fallen, but we will build with cut stone. The sycamore fig trees have been cut down, but we will put cedars in their place.”
Isaiah 9:11 Therefore Yahweh will set up on high against him the adversaries of Rezin, and will stir up his enemies,
The verse centers on "people", "including", "ephraim", "inhabitants", "samaria", "pride", "arrogance", and "heart". It is saying that the verse draws attention to "people" and "including", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "The Lord sent a word into Jacob..." into verse 10's "The bricks have fallen but we will...", so "people" and "including" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "people" and "including" with trust shaped by these words, not by a vague optimism outside the passage.
