אֲשֶׁ֣ר לֹא־יִ֭שְׁמַע לְק֣וֹל מְלַחֲשִׁ֑ים חוֹבֵ֖ר חֲבָרִ֣ים מְחֻכָּֽם׃
Which hearkeneth not to the voice of charmers, Or of the most cunning binder of spells.
Rashi on Psalms
Which will not hear, etc. This is connected to the preceding verse: “and it closes its ear in order not to hear the voice of charmers.”
