Monday of the Sixteenth Week in Ordinary Time

Matthew 12:38-42
Some of the scribes and Pharisees said to Jesus,
"Teacher, we wish to see a sign from you."
He said to them in reply,
"An evil and unfaithful generation seeks a sign,
but no sign will be given it
except the sign of Jonah the prophet.
Just as Jonah was in the belly of the whale three days and three nights,
so will the Son of Man be in the heart of the earth
three days and three nights."
