John Wesley on Isaiah 27:8

In measure - With moderation. When - When the vine shooteth forth its luxuriant branches, he cuts them off, but so as not to destroy the vine. Contend - God is said to contend with men, when he executes his judgments upon them, Amos 7:4. Stayeth - He mitigates the severity of the judgment. In the day - In the time when he sends forth his east - wind; which he mentions because that wind in those parts was most violent and most hurtful.
