blessed in him:

(Psa 72:17; KJV).
The importance of this verse for biblical theology
cannot be overstated.
Psalm 72 is rightly considered to be a psalm about the Messiah.
This psalm not only looks to the future, it also is deeply rooted in the past. It prophesies and interprets simultaneously.
Psalm 72:17 says
that all the nations of the earth
will be blessed in and through the Messiah.
This words of this prophecy have been taken nearly verbatim from Genesis,
God's promise to bless all nations through Abraham and his seed
(Gen 12:3; 18:18; 28:14).
To be clear, Psalm 72 provides us with a very obvious
Messianic interpretation of earlier Scripture.
Paul's commentary on the seed in Galatians 3:16, therefore, is not a reading backwards of the
Christian faith back onto the pages of
the Old Testament.
Rather, it is a reading of the Old Testament that correctly and ultimately leads those with eyes to see to Jesus! "Now the promises were spoken to Abraham and to his seed.
