'Today' in the Bible

if we are examined today concerning a good deed done to a crippled man, by what means this man has been healed,

that God has fulfilled the same to us, their children, in that he raised up Jesus. As it is also written in the second psalm, 'You are my Son. Today I have become your father.'

unless it is for this one thing that I cried standing among them, 'Concerning the resurrection of the dead I am being judged before you today!'"
