John Gill's Exposition of the Whole Bible
Psalms 45:14
She shall be brought unto the King in raiment of needlework,.... Not in her sins, and trader the sense and guilt of them; as souls are brought to Christ, at first conversion, under the drawings of the Father's grace; nor in the rags of her own righteousness; but in the robe of righteousness, and garments of salvation, the change of raiment Christ has put upon her, having before this caused her iniquities to pass from her; or in the shining robes of immortality and glory: for this introduction of the church to Christ, her King, Head, and Husband, will be upon the first resurrection; when she being as a bride adorned and prepared for her husband, will be brought unto him, and presented to him by himself, a glorious church, without spot or wrinkle, or any such thing: and she will be introduced, either by the angels, who will be employed in gathering the elect from the four winds; or by the ministers of the Gospel, who, at the general harvest, in the end of the world will bring their sheaves with them; those souls they have been the instruments of converting, comforting, and ripening for glory; who will be their joy and crown of rejoicing then; these will be brought in several companies, which joining together, will make up the general assembly and church of the firstborn, that will then be presented to Christ: or by Jehovah the Father, who, as he brought Eve to Adam, when he had formed her of his rib, and had prepared her as a helpmeet for him; so when all the elect of God are formed by divine grace, and are prepared as a bride for the bridegroom, he will then bring them unto him, and they shall be with him where he is, and behold his glory; which is what he prays his father for, John 17:24;
the virgins her companions that follow her shall be brought unto thee; such who are betrothed as chaste virgins to Christ, who strictly and chastely adhere unto him, love him in the singleness of their hearts; are incorrupt in faith and worship, and of pure and upright conversations; see Revelation 14:4; these are the "companions" of the church, who are partakers of the same grace, enjoy the same privileges, and share in the common salvation; and, as they are partners together in sufferings, they will be in glory: these "follow" the footsteps of the flock, walk after the church in the path of doctrine and duty; are followers of her, as she is of the Lord, in the word and ordinances, and in the exercise of faith and patience; these, even everyone, shall be brought unto the King, not one shall be lost, or left behind: whither they shall be brought, and the manner in which, are expressed in Psalms 45:15.
