Compare Douay-Rheims with King James Version side-by-side to understand the meaning.
Isaiah 28 opens a series of "woes" directed at the leaders of Ephraim and Judah who have made a "covenant with death." The setting is the fading "proud crown" of the drunkards of Ephraim, whose glory is like a flower withering in a fertile valley. This starts as a confrontation of those who mock the prophet’s teaching, dismissing it as "precept upon precept, line upon line." It establishes that when a people reject the clear, simple word of God, they are eventually forced to hear the "gibberish" of an invading army’s tongue.
The story follows the Lord’s response to their false security: the laying of a "tested stone, a precious cornerstone, of a sure foundation" in Zion. Isaiah describes the "hail" that will sweep away the refuge of lies and the "waters" that will overwhelm their hiding place. This portrayal of a total structural collapse shows that any alliance—especially one with Sheol—is destined to be annulled by the justice of the Creator. It highlights the "strange work" of God, who acts as the farmer who knows exactly when to plow and when to thresh, varying His methods to achieve a perfect harvest.
Theological meaning is found in the "Cornerstone" being the only point of stability in a world of sinking sand. It reveals that faith is not a passive sentiment but an active resting upon a foundation that God Himself has laid for the protection of His people. This chapter is fundamental for understanding that while God's judgment may seem "strange" to those who do not know Him, it is executed with the precision of a master craftsman. It highlights that the "covenant with death" is an illusion that only the Word can break. The fall of the proud crown now turns toward the siege of the City of David.
Jesus Christ is the Precious Cornerstone, the tested and sure foundation who was rejected by the builders but has become the head of the corner. He is the one in whom whoever believes "will not be in haste" (or put to shame), providing a refuge that the hail of judgment cannot touch. While the leaders of Judah sought a covenant with death, Christ has abolished death and brought life to light through the Gospel. The judgment on the scoffers now moves to the altar-hearth of Ariel.
