'Day' in the Bible

Ah! For the day! For the day of Yahweh is near. It will come like destruction from Shaddai.

Blow [the] trumpet in Zion, and sound the alarm on {my holy mountain}! Let all the inhabitants of the land tremble, for the day of Yahweh [is] coming --[it is] indeed near.

A day of darkness and gloom, a day of cloud and thick darkness, like the dawn spreads on the mountains, a great and strong army! There has been nothing like it from old, and after it nothing will be again {for generations to come}.

And Yahweh {utters} his voice before his army, because his encampment [is] very large; strong [is the] one who carries out his decree, for great [is] the day of Yahweh and exceedingly fearful. Who can endure it?

The sun will be changed to darkness, and the moon to blood, before the coming of the great and awesome day of Yahweh.

Commotion, commotion in the valley of decision! For the day of Yahweh [is] near in the valley of decision!

And it will happen on that day; the mountains will drip new wine, and the hills will flow with milk, and all the channels of Judah will flow with water. A spring from the house of Yahweh will come forth, and it will water the valley of Acacia Trees.
