Psalm 5:1-3 KJV
[1] Give ear to my words, O Lord, consider my meditation. [2] Hearken unto the voice of my cry, my King, and my God: for unto thee will I pray. [3] My voice shalt thou hear in the morning, O Lord ; in the morning will I direct my prayer unto thee, and will look up.

Upon Nehiloth?

According to this article, the mysterious identity and etymology of Nehiloth ranges from winnowing to a swarm of bees to a musical instrument.

I prefer to think that it is all of these things—a mystery, a winnowing, a cloud of bees, a low, a perforated vibrating wind instrument, ominous, breathing, an inheritance, a judgment, a way of singing a song about love and judgment with the ambiguity low hum or imminent storms.

This is the only place in the Bible where the word appears.
