'Day' in the Bible

And his sons went and held a feast in the house of each one upon his day; and they sent and called for their three sisters to eat and to drink with them.

Now it came to pass on the day when the sons of God came to present themselves before Jehovah, that Satan also came among them.

And it fell on a day when his sons and his daughters were eating and drinking wine in their eldest brother's house,

Again it came to pass on the day when the sons of God came to present themselves before Jehovah, that Satan came also among them to present himself before Jehovah.

After this opened Job his mouth, and cursed his day.

Let the day perish wherein I was born, And the night which said, There is a man-child conceived.

Let that day be darkness; Let not God from above seek for it, Neither let the light shine upon it.

Let darkness and the shadow of death claim it for their own; Let a cloud dwell upon it; Let all that maketh black the day terrify it.

Let them curse it that curse the day, Who are ready to rouse up leviathan.

When I lie down, I say, When shall I arise, and the night be gone? And I am full of tossings to and fro unto the dawning of the day.

Look away from him, that he may rest, Till he shall accomplish, as a hireling, his day.

He wandereth abroad for bread,'saying , Where is it? He knoweth that the day of darkness is ready at his hand.

They that come after shall be astonished at his day, As they that went before were affrighted.

The increase of his house shall depart; His goods'shall flow away in the day of his wrath.

That the evil man is reserved to the day of calamity? That they are led forth to the day of wrath?

Which I have reserved against the time of trouble, Against the day of battle and war?
