The mandrakes give a smell,
The word is translated “love-apples” an allusion to mandrake roots being an aphrodisiac which word “dudaim,” is here used, the generality of interpreters and commentators understand by it mandrakes; and so it is rendered by the Septuagint on Genesis 30:14; Mandrakes contain deliriant hallucinogenic tropane alkaloids and the shape of their roots often resembles human figures, they have been associated with a variety of superstitious practices throughout history (Wikipedia); but it is questionable whether the same plant that is known among us by that name is meant, since it is of a strong ill scented and offensive smell; It appears Christ here speaks of his church, the people of God, with their fragrancy, being clad with the garments given them by Christ, which smell of myrrh, aloes, and cassia, and are anointed with the savoury ointments of the grace of the Spirit; whose prayers are sweet odours; and their works, with their persons, accepted with God in Christ: or rather the graces of the Spirit in lively exercise may be meant; such as those lovely flowers of faith, hope, love, repentance, patience, self-denial, humility, thankfulness, and others;
and at our gates [are] all manner of pleasant [fruits];
in distinction from the mandrakes and flowers in the fields Genesis 30:14; and in allusion to a custom, in many countries, to garnish the posts of the door of newly married persons with branches of trees, and fruits, and flowers; and at other festivals, besides nuptial ones, which made it inviting to enter in: and these “all manner of pleasant [fruits]” may denote the plenty, variety, and excellency of the blessings of grace, and of the graces of the Spirit, believers have from Christ; and of the doctrines and ordinances of the Gospel, which are for their use; and may be said to be “at our gates,” as being ready at hand, in the hearts of saints, and in the mouths of Gospel ministers; and open and visible, held forth to public view in the word and ordinances; and which are administered at Wisdom’s gates, the gates of Zion, where they are to be met with and had. And which are new and old; denoting the plenty of grace and blessings of it, of old laid up in Christ, and from whom there are fresh supplies continually: or rather the doctrines of the Old and New Testament; which, for matter and substance, are the same; and with which the church, and particularly her faithful ministers, being furnished, bring forth out of their treasure things new and old, Matthew 13:52;
[which] I have laid up for thee, O my beloved;
Assuming Christ is speaking of the above fruits, they are the blessings, promises, and doctrines of grace, brought forth and made use of at proper times and seasons, for her own use and benefit, and of all believers, yet in all for the honour and glory of Christ, the author and donor of them. Respect may be had to a custom with lovers, to lay up fruits for those they love; at least such custom may be compared with this. Or, laid up meaning to come in glory—compare with Ps.31:19, II Tim.4:8, I Cor.2:9-10, things laid up for god’s people when they enter the gates of the heavenly Jerusalem (Rev.22:14). How great the goodness laid up for God’s people! (Anon).
