Barnes' Notes
"Iniquity" and "perverseness" are found together again in the Hebrew of Psalms 10:7; Psalms 90:10, and elsewhere; and import wickedness together with that tribulation which is its proper result.
The shout - The word is used (Leviticus 23:24 note) to describe the sound of the silver trumpets. The "shout of a king" will therefore refer to the jubilant sounds by which the presence of the Lord as their King among them was celebrated by Israel.
