What does Psalm 45:12 mean?

Tyre was a wealthy city on the coast of the Mediterranean Sea. When David was building his palace, Hiram, King of Tyre, recognized David's kingly position over Israel by sending gifts to him. Second Samuel 5:11 says, "And Hiram king of Tyre sent messengers to David, and cedar trees, also carpenters and masons who built David a house." In this psalm, an earthly king is being married (Psalm 45:1, 9). The terminology used allows for a prophetic interpretation: a preview of the ministry of Jesus Christ (Psalm 45:6–7; Hebrews 1:8–9).

At His birth, Jesus received gifts fit for a king from the wise men who traveled from the East in search of the king of the Jews (Matthew 2:1–2, 11). Someday, when Jesus, the Son of David and heir to his throne, resides in the New Jerusalem, the nations will bring their glory and honor into the city (Revelation 21:24–26). Today, it is the privilege of Jesus' followers to present gifts to Him. Among those gifts are themselves (Romans 12:1–2), thanks (1 Thessalonians 5:18), praise (Hebrews 13:15), obedience to His commands (John 15:1–17), love of others (Matthew 25:40; Galatians 6:9–10; 1 John 6:16–18; James 1:22, 27; 2:14–17), and financial offerings to support the work of ministry and help those in need (1 Corinthians 9:14; 2 Corinthians 8—9; Galatians 6:6).

Some interpreters believe the Hebrew of this verse should indicate that a "daughter," likely intending to be representative of the "people" or the nation in a diplomatic sense, of Tyre will approach the newly married couple with a present. Another view is that the people of Tyre will continue to honor the king of Israel with trade and gifts. Others suggest there might be a minor error in copies of the manuscript, slightly blurring the intended meaning.
