This Psalm is a tribute to a King on the occasion of his wedding. He is exalted and praised and so is his bride. She is arrayed in clothing made with gold fabric and adorned with gold ornaments. Yet we can easily see that the Psalm is also a Psalm of the Messiah. The King has a throne that is everlasting. This Psalm is fulfilled by Jesus who is the Messiah, the Savior, God incarnate. The bride then is spiritual Israel, the church who are the people He has chosen to be His own.
We note that the bride is called to forsake her family and her parents. The King, her husband, is her Lord now, the only one to whom she owes allegiance. She is to be totally devoted to him. In the same way we who are the bride of Christ are called also to forsake the world, to forsake even our families and devote ourselves totally to the Lord. We are not to cling to our old ways or our old sins; we are not to cling even to the ways or religious practices of our family. Every relationship we have must be rooted in and flow through our relationship with Jesus. That includes the marital relationship as well which is why the Lord speaks against interfaith marriages. The Lord is to be the center of the marriage. If one of the spouses does not worship the Lord, there will be division and disharmony for no one can serve 2 masters.
