41 - God brings one from the north and east to trample the nations, but Israel is His special treasure. The idols of the nations are as nothing.
42 - God's gentle servant will be light and justice for Gentiles. God saves those who trust Him; He turns away those who trust in idols. But now Israel is plundered for her sin.
43 -God will redeem Israel - only He is their savior - though they have wearied Him with their sins.
