The Song of Solomon barely made it into the Holy Scripture as a holy book among 66 books. But it did! Why!
Because it is the holiest of volumes as the holy of holies in Jehovah’s Temple when Solomon was king. God’s truth is in the Songs, and the ten women appear in the last days, and so why is it so strange that a maiden would appear from Gilead at the same time answering the women’s questions?
