'Evenings' in the Bible

Therefore a lion out of the forest shall kill them, a wolf of the evenings shall destroy them, a leopard shall watch against their cities; everyone who goes out there shall be torn in pieces; because their transgressions are many, [and] their backsliding is increased.

He said to me, To two thousand and three hundred evenings [and] mornings; then shall the sanctuary be cleansed.

The vision of the evenings and mornings which has been told is true: but seal up the vision; for it belongs to many days [to come].
