 2 Kings 9:35 (c) This peculiar incident may teach us the lesson that the thoughts and decisions of the wicked woman Jezebel remained to defile the people after she had gone from the scene. It may be that the palms of the hands remind us that the work which she did in persecuting the believers remained after she was unable to serve because of death.

International Standard Bible Encyclopedia [6]

skul ( גּלגּלת , gulgōleth  ; κρανίον , kranı́on ): The Hebrew word, which is well known to Bible readers in its Aramaic-Greek form "Golgotha," expresses the more or less globular shape of the human skull, being derived from a root meaning "to roll." It is often translated in English Versions of the Bible by "head," "poll," etc. In the meaning "skull" it is found twice (  Judges 9:53;  2 Kings 9:35 ). In the New Testament the word is found only in connection with Golgotha (which see), "the place of a skull" ( Matthew 27:33;  Mark 15:22;  John 19:17 ), or "the skull" ( Luke 23:33 ).
