When Ezekiel's wife died, what did God tell him not to do?

Answer: Mourn or weep

God took "the desire of your eyes" and told Ezekiel not to mourn or weep, a sign to the people. That evening his wife died.

““Son of man, behold, I am about to take away the desire of your eyes with a fatal blow. But you must not mourn or weep or let your tears flow.”— Ezekiel 24:16 (BSB)
