How do the rhetorical questions introduce Samaria’s warning?

The whole family brought from Egypt must hear God's word. Only they have been known among earth's families; therefore their iniquities will be visited. The edition explains visitation as punishment. Questions follow: can two walk without agreement, a lion roar without prey or a cub cry without having taken something, a bird fall without a fowler or a snare rise without a catch? A city's trumpet brings fear; can evil occur there without the Lord? The note distinguishes punishments of war, famine, pestilence and desolation from sin, of which God is not author. God reveals his secret to prophetic servants; as a roaring lion brings fear, his speech calls forth prophecy.

Azotus's and Egypt's houses are called to assemble on Samaria's mountains and see follies and oppression in its inner rooms. The people do not know right conduct, storing iniquity and robbery in houses. Tribulation surrounds the land, strength is removed and houses spoiled. Israel's removal is compared with a shepherd extracting two legs or an ear tip from a lion's mouth, applied to Samaria's bed-place and Damascus's couch. The house of Jacob must hear testimony: when transgressions are visited, Bethel's altar horns are cut to the ground, winter and summer houses struck and ivory and many houses destroyed. The chapter does not report an elite belief in guaranteed immunity or give a fixed numerical size of survivors.
