Jeremias 6:4

4 Prepare yourselves for war against her; rise up, and let us go up against her at noon. Woe to us! for the day has gone down, for the shadows of the day fail.

Jeremias 6:4 In-Context

2 And pride, O daughter of Sion, shall be taken away.
3 The shepherds and their flocks shall come to her; and they shall pitch tents against her round about, and shall feed each with his hand.
4 Prepare yourselves for war against her; rise up, and let us go up against her at noon. Woe to us! for the day has gone down, for the shadows of the day fail.
5 Rise, and let us go up against her by night, and destroy her foundations.
6 For thus saith the Lord, Hew down her trees, array a numerous force against Jerusalem. O false city; all oppression in her.
