The sign of Jonah

This thesis elaborates mainly from the three Bible passages of;

St. Matthew 12: 39, 40
"And he answering said to them, `A generation, evil and adulterous, doth seek a sign, and a sign shall not be given to it, except the sign of Jonah the prophet;"
 "for, as Jonah was in the belly of the fish three days and three nights, so shall the Son of Man be in the heart of the earth three days and three nights."

(And)

Acts 1:5
"because John, indeed, baptized with water, and ye shall be baptized with the Holy Spirit -- after not many days."

(Young's Literal Translation 1862)
