John Trapp on Psalms 47:4

Verſ. 4. He ſhall chuſe our inheritance for us] Or, He hath choſen, Of his free grace, he eſpied out the Land of Canaan for his people Iſrael, flowing with Milk; and Honey, and ſuch as was the glory of all Lands, Ezek, 20.6. and as much, yea much more hath he done for the whole Iſrael of God, both of Jews and Gentiles, by electing them to an inheritance immortal, undefiled, reſerved in Heaven for them, 1 Pet. 1.4.

The excellency (or high-glory) of Jacob whom he loved] i.e. All thoſe high and honourable Priviledges wherein Jacob once, and now all the faithful may wellglory and rejoyce. See Rom. 9.4.5. having as great both abundance and aſſurance of Gods grace and goodneſs, as Jacob ever had.
