So I should be the one who provides insight and understanding as you read this Psalm. I am puzzled and cannot find an answer, however, to vs.16. Who is this serving girl that is mentioned? The only educated guess that I can make, since I can’t find any of the commentaries which address this, is that this is actually Solomon who might be writing this Psalm. I know, it says Psalm of David, but as we have seen in the past just like artists who were around in the 15th and 16th century there were schools of art that were attributed to famous artists and so they are attributed with that work. Solomon, who was the son of Bathsheba, who could be considered a serving girl, just might be the author of this psalm.
If this is the case then that is ironic, because he begins the psalm by claiming that he is poor, and yet Solomon is considered not only one of the wisest leaders in history, but also one of the wealthiest.
Vs. 8 makes me think of this song. I’ll leave you with this.
