How do Calvinists explain Luke 19:41-44

How do Calvinists explain Luke 19:41-44: > 41 And when he drew near and saw the city, **he wept over it**, 42 > saying, “Would that you, even you, had known on this day the things > that make for peace! But now they are hidden from your eyes. 43 For > the days will come upon you, when your enemies will set up a barricade > around you and surround you and hem you in on every side 44 and tear > you down to the ground, you and your children within you. And they > will not leave one stone upon another in you, because you did not know > the time of your visitation.” Why would Jesus weep for non-elect people if He Himself willfully passed over them when He elected people unto salvation before the foundation of the world?
