God here goes on to threaten what he would do with this treacherous idolatrous people; and he warns that he may not wound, he threatens that he may not strike. If he turn not, he will whet his sword (Ps. vii. 12); but, if he turn, he will sheathe it. They did not turn, and therefore all this came upon them: and its being threatened before shows that it was the execution of a divine sentence upon them for their wickedness; and it is written for admonition to us.
