Be careful not to forget the covenant of the LORD your God that he made with you; do not make for yourselves an idol in the form of anything the LORD your God has forbidden. (Deu 4:23 NIV) and Jesus answered: “A wicked and adulterous generation asks for a sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth. (Mat 12:39-40 NIV)
