In verse 18, Yahweh stops speaking directly to Jehoiakim and begins to speak to other people. Here "lament" refers to grieving at Jehoiakim's death. Alternate translation: "They will not lament for Jehoiakim when he dies" (See: [[rc://en/ta/man/translate/figs-explicit]])
# Woe, my brother! ... Woe, my sister! ... Woe, master! ... Woe, majesty!
Yahweh uses the word "Woe" several times for emphasis. He addresses the various people who would normally show great sadness when someone dies. (See: [[rc://en/ta/man/translate/figs-parallelism]])
