As Jonah was in the belly of the sea-monster for three days and three nights, so will the Son of Man be in the heart of the earth for three days and three nights.
Matthew 12:40

Jesus answered them, “Destroy this temple, and I will raise it again in three days.” They replied, “It has taken forty-six years to build this temple, and you are going to raise it in three days?” But the temple he had spoken of was his body. After he was raised from the dead, his disciples recalled what he had said. Then they believed the scripture and the words that Jesus had spoken.
John 2:18-22
