John Wesley on Psalms 45:9

Among - Among them that attend upon thy spouse, as the manner was in nuptial solemnities. As the queen is the church in general, and so these honourable women are particular believers, who are daily added to the church, Acts 2:47. And although the church is made up of particular believers, yet she is distinguished from them, for the decency of the parable. And these believers may be said to be Kings daughters, because among others, many persons of royal race embraced the faith, and because they are in a spiritual sense, Kings unto God, Rev 1:6. Right hand - The most honourable place. Ophir - Clothed in garments made of the choicest gold. By which he designs the graces wherewith the church is accomplished.
