4 And now shall the spoils of your small and great be gathered: as if one should gather locusts, so shall they mock you.
5 The God who dwells on high is holy: Sion is filled with judgment and righteousness.
6 They shall be delivered up to the law: our salvation is our treasure: there are wisdom and knowledge and piety toward the Lord; these are the treasures of righteousness.
7 Behold now, these shall be terrified with fear of you: those whom ye feared shall cry out because of you: messengers shall be sent, bitterly weeping, entreating for peace.
8 For the ways of these shall be made desolate: the terror of the nations has been made to cease, and the covenant with these is taken away, and ye shall by no means deem them men.
