2 Kings 23:6

And he brought out the grove... — The Asherah set up by Manasseh (2 Kings 21:3; 2 Kings 21:7), and removed by him on his repentance (2 Chronicles 33:15), but restored (probably) by Amon (2 Kings 21:21).

Unto the brook... at the brook. — Unto the ravine... in the ravine, or wady.

The graves of the children (sons) of the people — i.e., the common graves (Jeremiah 26:23); a mark of utter contempt: 2 Chronicles 34:4 paraphrases, “the graves of them that sacrificed unto them.”
