Sforno on Numbers 6:26/ספורנו על במדבר ו׳:כ״ו

1ישא ה' פניו אליך, giving you a vista of the world to come which awaits you. The line is similar in essence to what David said in Psalms 36,10 כי עמך מקור חיים באורך נראה אור, “with You is the fountain of life; by Your light do we see light.” It also reflects the statement of our sages in B’rachot 17 that in the world of the future the righteous sit with their crowned heads and enjoy the radiations of G’d’s glory.

2וישם לך שלום, the serenity of peace which is equivalent to an infinite, unbroken and undisturbed existence, not tainted by punishment, something which is a feature of life in the world to come.
