Jeremias 49:20

20 that ye have wrought wickedness in your hearts, when ye sent me, saying, Pray thou for us to the Lord; and according to all that the Lord shall speak to thee we will do.

Jeremias 49:20 In-Context

18 For thus saith the Lord; As my wrath has dropped upon the inhabitants of Jerusalem, so shall my wrath drop upon you, when ye have entered into Egypt: and ye shall be a desolation, and under the power of others, and a curse and a reproach: and ye shall no more see this place.
19 which the Lord has spoken concerning you the remnant of Juda; Enter ye not into Egypt: and now know ye for a certainty,
20 that ye have wrought wickedness in your hearts, when ye sent me, saying, Pray thou for us to the Lord; and according to all that the Lord shall speak to thee we will do.
21 And ye have not hearkened to the voice of the Lord, with which he sent me to you.
22 Now therefore ye shall perish by sword and by famine, in the place which ye desire to go into to dwell there.
