And turning toward the east, Paul lifted up his hands to heaven and prayed much; and after having conversed in Hebrew with the fathers during prayer, he bent his neck, without speaking any more. When the lictor cut off his head, milk splashed on the dress of the soldier. And the soldier, and all who stood near by, were astonished at this sight and glorified God, who had thus honored Paul. And they went away and reported everything to Caesar.
