The Bible doesn't record any events on this day, Wednesday before the day Jesus rose from the dead.
Did He spend the day in prayer?
Did He visit that day for the last time with His friends Lazarus, Martha, and Mary?
Did He teach that day in the temple?
Was this the day they would sacrifice the lamb they would eat for dinner on Friday?
Or was He exhausted from the anguish of this week and just rested?
If you knew you would die this week, what would you be doing?
