Yehezkiel 30:18-19

30:18 In Tahpanhes the day will be dark ¹ 

when I break the yoke of Egypt there.

Her confident pride will cease within her;

a cloud will cover her, and her daughters will go into captivity.

30:19 I will execute judgments on Egypt.

Then they will know that I am the Lord.’”

[30:18]  ¹ sn In Zeph 1:15 darkness is associated with the day of the Lord.
