7133. Saying, Complete ye your works, the work of a day in its day. That this signifies that they should serve falsities so called in every state, is evident from the signification of “completing your works,” as being to serve falsities; for by “making bricks” are signified things fictitious and false that are injected (see n. 7113), and as these are the works which they were to complete, it signifies that they should serve these; it is said “falsities so called,” because the evil do not acknowledge the falsities which they speak as being falsities, but as being truths; and from the signification of “the work of a day in its day,” as being in every state (that a “day” denotes state, see n. 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850).

23. Nothing is more common in the Word than for “day” to be used to denote time itself. As in Isaiah:

The day of Jehovah is at hand. Behold, the day of Jehovah cometh. I will shake the heavens, and the earth shall be shaken out of her place, in the day of the wrath of Mine anger. Her time is near to come, and her days shall not be prolonged (Isaiah 13:6, 9, 13, 22).

And in the same Prophet:

Her antiquity is of ancient days. And it shall come to pass in that day that Tyre shall be forgotten seventy years, according to the days of one king (Isaiah 23:7, 15).

As “day” is used to denote time, it is also used to denote the state of that time, as in Jeremiah:

Woe unto us, for the day is gone down, for the shadows of the evening are stretched out (Jeremiah 6:4).

And again:

If ye shall make vain My covenant of the day, and My covenant of the night, so that there be not day and night in their season (Jeremiah 23:20, 25).

And again:

Renew our days, as of old (Lamentations 5:21).
