Psalms 45:11

So shall the King greatly desire thy beauty
Which lies in the comeliness or righteousness of Christ put upon her; in the holiness of Christ reckoned to her; in being washed from all sin in the blood of Christ; in the graces of the Spirit being implanted in her, in which the beauty of holiness lies; in the salvation she is interested in, and beautified with; in enjoying the order and ordinance of Christ's house, and in having the presence of God and Christ with her: and this beauty is not natural, nor acquired by her, but what is given her; it is not an outward, but an inward beauty; nor is it fictitious, but real; it is perfect through the comeliness of her Lord upon her; and it is durable as the olive tree: and this is greatly desired by Christ, who delights in her, and to behold her countenance; seeks after her company, and will have her where he is, that she may behold his glory, and he may behold her beauty;

for he [is] thy Lord;
not only by creation, but by redemption, and in right of marriage, as well as on account of other relations he stands in to her, as Father, Head, King, and Master; and it is her privilege that he is her Lord, as well as her duty to own the relation; since, though he is a sovereign Lord, he is no tyrannical one, but governs with gentleness, and he has all power to protect her, and all fulness to supply her wants; and on account of his being her Husband, Lord, and Head, he has a right of worship from her, as follows;

and worship thou him;
both internally, by the exercise of faith, hope, and love upon him; and externally, by praying to him, praising of him, and attending on all his ordinances, and doing everything in a religious way, in his name, according to his word, and by his authority; and such worship should be in spirit and in truth, in sincerity, and without hypocrisy, in righteousness and true holiness, and with reverence and godly fear.
