"Perhaps they will bring their petition before the LORD, and will all turn from their wicked ways, for the anger and wrath pronounced against this people by the LORD are great." (NIV)
It may be that they will make their supplication [for mercy] before the Lord, and each one will turn back from his evil way, for great is the anger and the wrath that the Lord has pronounced against this people. (AMP)
It may be they will present their supplication before the LORD, and will return every one from his evil way: for great is the anger and the fury that the LORD hath pronounced against this people. (KJV)
