Yeremia 43:7

43:7 They went on to Egypt ¹  because they refused to obey the Lord, and came to Tahpanhes. ² 

Yehezkiel 30:18

30:18 In Tahpanhes the day will be dark ³ 

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.

[43:7]  ¹ sn This had been their intention all along (41:17). Though they consulted the Lord and promised to do what he told them whether they agreed with it or not (42:5-6), it is clear that they had no intention of doing so. Jeremiah could see that (42:19-22). They refused to believe that the Lord had really said what Jeremiah told them (43:4) and feared reprisal from the Babylonians more than any potential destruction from the Lord (43:3).

[43:7]  ² sn Tahpanhes was an important fortress city on the northern border of Egypt in the northeastern Nile delta. It is generally equated with the Greek city of Daphne. It has already been mentioned in 2:16 in conjunction with Memphis (the Hebrew name is “Noph”) as a source of soldiers who did violence to the Israelites in the past.

[30:18]  ³ sn In Zeph 1:15 darkness is associated with the day of the Lord.
