Albert Barnes Commentary Jeremiah 26:23

"and they fetched forth Uriah out of Egypt, and brought him unto Jehoiakim the king, who slew him with the sword, and cast his dead body into the graves of the common people." — Jeremiah 26:23 (ASV)

Out of Egypt - As Jehoiakim was a vassal of Egypt, he would easily obtain the surrender of a man accused of treason.
