How do we know who is actually speaking in Song of Solomon? Are there markings in the Hebrew manuscripts that point to who is speaking, or are the scholars simply assuming based on what they are reading who is speaking? (For some Bibles mark who is speaking through letters next to the passage and an explanation in the footnotes)
For example Song of Solomon 8:5-7:
5... Beneath the apple tree I awakened you; There your mother was in labor with you, There she was in labor and gave you birth. 6 Put me like a seal over your heart, Like a seal on your arm. For love is as strong as death, Jealousy is as severe as Sheol; Its flashes are flashes of fire, The very flame of the Lord. 7 Many waters cannot quench love, Nor will rivers overflow it; If a man were to give all the riches of his house for love, It would be utterly despised. (NASB1995)
My Bible marked that the bride is speaking here. Are the translators simply giving their opinion or is there hard evidence in the manuscripts that the bride is speaking instead of the bridegroom?
