10, 11. Weep . . . not for--that is, not so much for Josiah, who was taken away by death from the evil to come (2Ki 22:20; Isa 57:1); as for Shallum or Jehoahaz, his son (2Ki 23:30), who, after a three months' reign, was carried off by Pharaoh-necho into Egypt, never to see his native land again (2Ki 23:31-34). Dying saints are justly to be envied, while living sinners are to be pitied. The allusion is to the great weeping of the people at the death of Josiah, and on each anniversary of it, in which Jeremiah himself took a prominent part (2Ch 35:24, 25). The name "Shallum" is here given in irony to Jehoahaz, who reigned but three months; as if he were a second Shallum, son of Jabesh, who reigned only one month in Samaria (2Ki 15:13; 2Ch 36:1-4). Shallum means "retribution," a name of no good omen to him [GROTIUS]; originally the people called him Shallom, indicative of peace and prosperity. But Jeremiah applies it in irony. 1Ch 3:15, calls Shallum the fourth son of Josiah. The people raised him to the throne before his brother Eliakim or Jehoiakim, though the latter was the older (2Ki 23:31, 36; 2Ch 36:1); perhaps on account of Jehoiakim's extravagance (Jer 22:13, 15). Jehoiakim was put in Shallum's (Jehoahaz') stead by Pharaoh-necho. Jeconiah, his son, succeeded. Zedekiah (Mattaniah), uncle of Jeconiah, and brother of Jehoiakim and Jehoahaz, was last of all raised to the throne by Nebuchadnezzar.
      He shall not return--The people perhaps entertained hopes of Shallum's return from Egypt, in which case they would replace him on the throne, and thereby free themselves from the oppressive taxes imposed by Jehoiakim.
