Isaiah 29:20

the terrible one or "tyrant" probably denotes an external oppressor (the Assyrian); cf. Isaiah 25:3-4; the scorneris the despiser of religion (ch. Isaiah 28:14; Isaiah 28:22; Psalms 1:1, &c.).

all that watch for iniquity Perhaps "those who are wakefully intent upon plans of mischief" (Micah 2:1; Amos 8:5). Some think the phrase is ironical, implying that those spoken of were appointed to watch over right, but betrayed their trust in the manner described in Isaiah 29:21.
