Rashi on Lamentations
For it is Your doing. You caused them to hate me when You separated me from [partaking of] their food and drink and from intermarrying with them. If I had intermarried with them, they would have had compassion upon me and upon their daughters’ children.
Rashi on Lamentations
Bring the day that You proclaimed. If only you had brought upon them the appointed day that You proclaimed upon me.
