Dict: easton - Muth-labben

easton:

Muth-labben @ occurring only in the title of kjv@Psalms:9. Some interpret the words as meaning "on the death of Labben," some unknown person. Others render the word, "on the death of the son;" i.e., of Absalom ( kjv@2Samuel:18:33). Others again have taken the word as the name of a musical instrument, or as the name of an air to which the psalm was sung.
