Charles Ellicott Commentary Jeremiah 47:6

"O thou sword of Jehovah, how long will it be ere thou be quiet? put up thyself into thy scabbard; rest, and be still." — Jeremiah 47:6 (ASV)

O thou sword of the Lord ... —This is the question and entreaty of the Philistines, “When will there be an end of war?” And the prophet has but one answer: the sword must do its work till it has done what Jehovah had appointed it to do.
