The privileged position of the people of Israel compared to other nations is put into words here.
See also Deuteronomy 4:8. How wonderful it is that, thanks to God’s revelation, you do not have to grope blindly like a mole for the truth. Compare this with Romans 10:8. This gives us all the more reason to do what the psalm ends with: Praise the Lord!
20 Il n'a pas agi de même pour toutes les nations,Et elles ne connaissent point ses ordonnances.Louez l'Eternel!
