John Calvin Commentary Psalms 45:12

"And the daughter of Tyre [shall be there] with a gift; The rich among the people shall entreat thy favor." — Psalms 45:12 (ASV)

And the daughter of Tyre with a gift. This also is a part of the recompense which the prophet promises to the queen in order to mitigate or rather to extinguish entirely, the longing desire she might still feel for her former condition. He says that the Tyrians will come humbly to pay her reverence, bringing presents with them.

Tyre, we know, was formerly a city of great renown, and, therefore, he accounts it a very high honor that men will come from a city so distinguished and opulent to greet her and to testify their submission to her. It is not necessary for us to examine every word minutely in order to apply to the Church everything said here concerning the wife of Solomon; but in our own day we experience some happy fruits of this prophecy when God has so ordered it that some of the great men of this world, although they themselves refuse to submit to the authority of Christ, act with kindness towards the Church, maintaining and defending her.
