45:10-11 The psalmist gave some good advice to the bride. She would be wise to make her husband her primary object of affection (cf. Gen. 2:24). This would make her even more attractive to him. She should also honor him because he was now her authority (cf. Gen. 2:18).
45:12 If she followed this advice, she would enjoy the love and respect of other powerful people. Tyre was a Phoenician seaport. The Phoenicians were world travelers and traders. A gift from the daughter of the king of Tyre would therefore be very desirable. Other powerful people would also court the bride's favor if she glorified her worthy husband.
45:13-15 The bride was the daughter of a king herself. In these verses the psalmist pictured her coming into the palace for her marriage to her husband.
