The second-to-last stanza, verses 15-17, is a culmination and conclusion of the inaugural prayer-psalm. The stanza that follows (18-19) is a doxology that the newly anointed king’s subjects recited, an “Amen to that brother!”
Here, the orator asks God for one blessing after another to fall on the king: long life, gold, continual prayers and all day blessings from his subjects, plenty of grain, his subjects flourishing, his name endures forever, and finally, all nations be blessed through him, and they will call him blessed.
“The Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: ‘All nations will be blessed through you,’ God said to Abraham, and now repeated in this psalm. So those who have faith are blessed along with Abraham, the man of faith.” (Galatians 3:8-9) Now, the blessing of King of kings is also the blessings of the people who say, “Amen to that brother!” Let your King and all created hear our “AMEN!”
