2. They pretended reformation, but neither was that sincere, v. 16. Here is, (1.) The sin of Israel: They return, that is, they make as if they would return; they pretend to repent and amend their doings, but they make nothing of it; they do not come home to God nor return to their allegiance, whereas God says (Jer. iv. 1), If thou wilt return, O Israel! return to me; do not only turn towards me, but return to me. This dissimulation of theirs makes them like a deceitful bow, which looks as if it were fit for business, and is bent and drawn accordingly, but, when strength comes to be laid to it, either the bow or the string breaks, and the arrow, instead of flying to the mark, drops at the archer's foot. Such were their essays towards repentance and reformation. (2.) The sin of the princes of Israel. That which is charged upon them is the rage of their tongue, quarrelling with God and his providence and with all about them when they are crossed. Princes think they may say what they will, and that it is their prerogative to huff and bluster, to curse and rail, and to call names at their pleasure, but let them know there is a God above them that will call them to an account for the rage of their tongues and make their own tongues to fall upon them. (3.) The punishment of Israel and their princes for their sin. As for the princes, they shall fall by the sword either of their enemies or of their own people, some by one and some by the other; and this shall be their derision, this is that for which they shall be derided in the land of Egypt, when they flee to the Egyptians for succour, v. 11. Their sin and punishment shall make them a laughing-stock to all about them. Note, Those that are treacherous and deceitful in their dealings with God, and passionate and outrageous in their conduct towards men, will justly be made a derision to their neighbours, for they make themselves ridiculous.
