7:15 Bound - As a surgeon binds up a weak member, or a broken one; so did God for Ephraim, when the Syrians and other enemies had broken their arms. Imagine mischief - They devise mischief against my prophets, and let loose the reins to all impieties.
7:8-16 Israel was as a cake not turned, half burnt and half dough, none of it fit for use; a mixture of idolatry and of the worship of Jehovah. There were tokens of approaching ruin, as grey hairs are of old age, but they noticed them not. The pride which leads to break the law of God leads to self-flattery. The mercy and grace of God are the only refuge to which obstinate sinners never think of fleeing. Though they may howl forth their terrors in the form of prayers, they seldom cry to God with their hearts. Even their prayers for earthly mercies only seek fuel for their lusts. Their turning from one sect, sentiment, form, or vice, to another, still leaves them far short of Christ and holiness. Such are we by nature. And such shall we prove if left to ourselves. Create in us a clean heart, O God, and renew a right spirit within us.
