Matthew Poole and continuators on Song of Solomon 1:13

13 A bundle of mirrh is my beloved unto me ; he shall lie all night betwixt my breasts .

Or, A bag of mirrhe, in which there was a considerable quantity of the Gum which droppeth from the Mirrhe Tree. Mirrhe is bitter to the taste, but sweet to the smell, and therefore was ever reckoned amongst the best perfumes. See Exod. 30. 23. Psal. 45 8. Ioh. 19. 39.

He is most precious and comfortable to me, and the Author of my sweet smell last mentioned.

In the place where bundles or bags of Mirrhe, or other persumes hung down, being fastened about their Necks, which yet were taken away, and laid aside by night. But the Church intimates that she will not part with Christ, neither day nor night. Or this Phrase may note the Churches intimate Union with, and hearty Affection unto Christ.
