“On that day,

There shall not be

Either cold

Or frost.

There shall be a continuous day.

It is known to Yahweh.

There will be no day.

There will be no night.

At evening time,

There shall be light.”

On this glorious day of victory, there would be neither cold nor ice, since the temperature would be perfect.  There would be continuous daylight, without any night.  Even at evening time, there would be light.
