Anas (אֲנַס) in Aramaic means to distress, trouble, or oppress. This form appears in Daniel 4:9 where Nebuchadnezzar describes Daniel as one in whom is the spirit of the holy gods, and no mystery troubles him. It is cognate to the Hebrew H597 but used in the Aramaic portions of Daniel.
Daniel's freedom from being troubled or distressed by mysteries stands as evidence of divine wisdom granted to the humble. While Nebuchadnezzar's own spirit was troubled (Daniel 2:1), God's servant Daniel had access to revelation. This reflects the New Testament promise: "Do not let your hearts be troubled. You believe in God; believe also in me" (John 14:1). Spirit-filled believers need not be distressed by life's mysteries — God discloses what they need to know.
