Commentary for Psalms 72:3

May the mountains bear peace for the people in his days.

peace for the people. Now what is the peace that the mountains bear? When they produce fruit, people will not be jealous, and “each man will call his neighbor [to come] under [his] vine and under [his] fig tree.”

and the hillsthrough righteousness And the hills will bear peace for them through the righteousness that they will perform.
