Jeremiah 47:4-8

Because of the day that cometh to spoil all the Philistines, and to cut off from Tyrus and Zidon every helper that remaineth: for the LORD will spoil the Philistines, the remnant of the country of Caphtor.

Baldness is come upon Gaza; Ashkelon is cut off with the remnant of their valley: how long wilt thou cut thyself?

O thou sword of the LORD, how long will it be ere thou be quiet? put up thyself into thy scabbard, rest, and be still.

How can it be quiet, seeing the LORD hath given it a charge against Ashkelon, and against the sea shore? there hath he appointed it.
