וּרְאֵֽה־בָנִ֥ים לְבָנֶ֑יךָ שָׁ֝ל֗וֹם עַל־יִשְׂרָאֵֽל׃
Obyś oglądał dzieci dzieci twoich, pokój w Izraelu.

And may you see children [born] to your children and they shall not come to quarrel about halitzah, [since that is performed only if there are no children,] and then there will be peace upon Israel (addendum).
Rashi on Psalms
children [born] to your children They will inherit the estate, and no woman will be subject to the levir [in a levirate marriage]. Then there will be peace in the world.
