'Day' in the Bible

And his sons used to go and hold a feast {at each other's house} on his day, and they would send, and they would invite their three sisters to eat and to drink with them.

And it happened {one day} {that} the sons of God came to present themselves before Yahweh, and Satan also came into their midst.

And then [there] was one day when his sons and his daughters were eating and drinking wine in their firstborn brother's house.

{And then} one day the sons of God came to present themselves before Yahweh, and Satan also came into their midst to present himself before Yahweh.

{Afterward} Job opened his mouth and cursed his day.

"Let [the] day perish on which I was born, and the night that said, 'A man-child is conceived.'

Let that day become darkness; may God not seek it from above, nor may daylight shine on it.

Let darkness and deep shadow claim it; let clouds settle on it; let them terrify it [with the] blackness of day.

Let those who curse the day curse it, those who are skilled at rousing Leviathan.

"He is wandering for bread, [saying], 'Where [is it]?' He knows that a day of darkness [is] ready {at hand}.

The products of his house will be carried away [like] gushing waters on the day of his wrath.

Indeed, [the] wicked is spared from [the] day of disaster; he is delivered from [the] day of wrath.

He digs through houses in the darkness; by day they shut themselves in-- they do not know [the] light

which I have reserved for [the] time of trouble, for [the] day of battle and war?
