Arcana Coelestia #23
23. Nothing is more common in the Word than for the word 'day' to be used to mean the particular time at which events take place, as in Isaiah,
The day of Jehovah is near. Behold, the day of Jehovah comes. I will make heaven tremble, and the earth will be shaken out of its place, on the day of My fierce anger. Its time is close at hand, and its days will not be prolonged. Isaiah 13:6, 9, 13, 22.
And in the same prophet,
Her antiquity is in the days of antiquity. On that day Tyre will be forgotten for seventy years, like the days of one king. Isaiah 23:7, 15.
Since 'day' stands for the particular time it also stands for the state associated with that particular time, as in Jeremiah, Woe to us, for the day has declined, for the shadows of evening have lengthened! Jeremiah 6:4
And in the same prophet,
If you break My covenant that is for the day and My covenant that is for the night, so that there is neither daytime nor night at their appointed time. Jeremiah 33:20, 25.
Also,
Renew our days as of old. Lamentations 5:21.
Genesis 2:18-22
18
Yahweh God said, "It is not good that the man should be alone; I will make him a helper suitable for him."
19
Out of the ground Yahweh God formed every animal of the field, and every bird of the sky, and brought them to the man to see what he would call them. Whatever the man called every living creature, that was its name.
20
The man gave names to all livestock, and to the birds of the sky, and to every animal of the field; but for man there was not found a helper suitable for him.
21
Yahweh God caused a deep sleep to fall on the man, and he slept; and he took one of his ribs, and closed up the flesh in its place.
22
He made the rib, which Yahweh God had taken from the man, into a woman, and brought her to the man.
