26:19-20 The Lord further promised that after He destroyed the city by deluging it with great waves of invaders (cf. v. 3), it would die like a person placed in a grave (cf. 31:16; 32:18, 23-25, 29-30). It would go down into Sheol, as it were, and so lose its glory. He pictured the island fortress as submerged beneath the sea of invaders that would bury it (cf. 31:14-18; 32:13-32; Isa. 14:4-21).
"The most fearful prospect facing ancient mariners was to be caught in a storm and be lost at sea.'"365
Ezekiel mixed two metaphors for destruction in these verses: waves overwhelming a rocky seaside town, and a person going into the grave (pit, Sheol).
26:21 Terrors would overtake the people, and the city would exist no longer even though others tried to find it (cf. 27:26-35). They would search for the city on its former site but would discover that it was not there. In other words, it would enjoy no continuing importance in history. Today only a small fishing village exists on the site, and sailors use the rocks to dry their nets (cf. v. 14).
