Matthew 12:38-42 - The Sign Of Jonah
38 Then certain experts in the law of Moses and some Pharisees answered Jesus, saying, "Teacher, we would like to see you perform a [supernatural] sign."
39 But He said to them, "It is [only] an evil and unfaithful [i.e., to God] generation of people that looks for a [supernatural] sign. And there will not be any sign given to it except the [supernatural] sign [demonstrated in the life] of Jonah, the prophet. 40 For just like Jonah was in the stomach of the huge fish for three days and nights, so the Son of man will be in the heart of the earth [i.e., the cave-tomb] for three days and nights. 41 The people of Nineveh will stand up on the judgment day along with the people of this generation and will condemn them because they repented [i.e., changed their hearts and lives] when hearing the preaching of Jonah [See Jonah 3:5-10], and [now] Someone greater than Jonah is here [i.e., Jesus]. 42 The queen of the South [Note: This queen was from Sheba, I Kings 10:1, which was probably in Arabia] will stand up on the judgment day along with the people of this generation and will condemn them because she came from a great distance to hear [and see] Solomon's wisdom [I Kings 10:1ff] and [now] Someone greater than Solomon is here [i.e., Jesus].
29 And when the crowds thronged around Jesus, He began saying, "This generation of people is evil, [for] it is looking for a [supernatural] sign. But no [such] sign will be given to it except the sign [demonstrated in the life] of Jonah. 30 For just like Jonah became a sign to the people of Nineveh [Note: Nineveh was the capital of ancient Assyria], so the Son of man will also be [a sign] to this generation of people. 31 The queen of the South [Note: This queen was from Sheba, which was probably in Arabia. See I Kings 10:1] will stand up on the judgment day, along with the people of this generation, and will condemn them because she came from a great distance to hear [and see] Solomon's wisdom [I Kings 10:1ff] and [now] Someone greater than Solomon is here [i.e., Jesus]. 32 The people of Nineveh will stand up on the judgment day with the people of this generation and will condemn them because they repented [i.e., changed their hearts and lives] when hearing the preaching of Jonah [Jonah 3:5-10] and [now] Someone greater than Jonah is here [i.e., Jesus].
