John Wesley on Amos 6:1

At ease - That neither fear nor believe the threatened judgments of God. In Zion - That is put for the kingdom of the two tribes, and principally the inhabitants of Jerusalem. Samaria - Woe to them also who rely upon the strength, wealth, and policy of the kingdom of Samaria or Israel. Which - Which two cities, Zion and Samaria. Named chief - Accounted the chief cities of that part of the world. To whom - To which place all Israel had recourse, the two tribes to Zion, the ten tribes to Samaria.
