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.

15. I … bound—when I saw their arms as it were relaxed with various disasters, I bound them so as to strengthen their sinews; image from surgery [Calvin]. Maurer translates, "I instructed them" to war (Ps 18:34; 144:1), namely, under Jeroboam II (2Ki 14:25). Grotius explains, "Whether I chastised them (Margin) or strengthened their arms, they imagined mischief against Me." English Version is best.
