Nevertheless for thy great mercies' sake thou didst not utterly consume them, nor forsake them; for thou [art] a gracious and merciful God.
Ver. 31. Nevertheless for thy great mercies' sake] Man's perverseness cannot interrupt the course of God's goodness. In the midst of judgment he remembereth mercy, which beareth the same proportion to his judgment which seven (a complete number) hath to a unity.
Thou didst not utterly consume them] God will repent for his people, when he seeth their power is gone, Deuteronomy 32:36, and be jealous with a great jealousy when the enemy goes beyond his commission, Zechariah 1:14,15 .
For thou art a gracious and merciful God] And this is most seen when misery weighs down, and nothing but mercy turneth the scale.
