939 B
They will strike you down to the ground and your children with you
Jesus is speaking to the people of the city as if he were speaking to the city itself as he would speak to a woman. He speaks of the people who live in the city as if they are the woman's children, and thus the city's children. To strike down a city is to destroy its walls and buildings, and to strike down its children is to kill those who live in it. Alternate translation: "They will completely destroy you and kill all who live in you" or "They will completely destroy your city and kill all of you" (See: rc://en/ta/man/translate/figs-apostrophe)
They will not leave one stone upon another
"They will not leave any of the stones in place." This is a hyperbole to express that the enemies will completely destroy the city, which is built of stones. (See: rc://en/ta/man/translate/figs-hyperbole)
