Todd Beamer dad to 2 young sons then 3 and 1-years-old, on his last call out from Flight 93 asked the operator to call his family, pray with him and they recited the 23rd psalm together, before Todd and others on the plane counter attacked the hijackers.
The LORD Is My Shepherd
23The Lord is my shepherd; I shall not want. 2 He maketh me to lie down in green  pastures: he leadeth me beside the still waters. 3 He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake. 4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. 5 Thou preparest a table before me in the presence of mine enemies: thou anointest  my head with oil; my cup runneth over. 6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever.
