Jamieson, Fausset and Brown on Song of Solomon 1:12

12. While--It is the presence of the Sun of Righteousness that draws out the believer's odors of grace. It was the sight of Him at table that caused the two women to bring forth their ointments for Him (Lu 7:37, 38; Joh 12:3; 2Co 2:15). Historically fulfilled (Mt 2:11); spiritually (Re 3:20); and in church worship (Mt 18:20); and at the Lord's Supper especially, for here public communion with Him at table amidst His friends is spoken of, as So 1:4 refers to private communion (1Co 10:16, 21); typically (Ex 24:9-11); the future perfect fulfilment (Lu 22:30; Re 19:9). The allegory supposes the King to have stopped in His movements and to be seated with His friends on the divan. What grace that a table should be prepared for us, while still militant (Psa 23:5)!

my spikenard--not boasting, but owning the Lord's grace to and in her. The spikenard is a lowly herb, the emblem of humility. She rejoices that He is well pleased with her graces, His own work (Php 4:18).
