But He answered and said to them, “An evil and adulterous generation seeks after a sign, and no sign will be given to it except the sign of the prophet Jonah. Matthew 12:39

“And having answered, He said to them, ‘Generation – evil and adulteress – it seeks a sign, and not it will be given it, if not the sign of Jonah the prophet’” (CG).

In the previous verse, some scribes and Pharisees came to Jesus, saying that they wanted to see a sign from Him. In response, Matthew next records, “And having answered, He said to them, ‘Generation – evil and adulteress – it seeks a sign.’”

The noun moichalis, an adulteress, is introduced. Almost all translations say adulterous, the adjective form of the word. This is incorrect. It is a feminine noun referring to a female who is unfaithful.

As throughout the Old Testament, Jesus equates the relationship of the Lord with His people as a covenant of marriage. A wife was to be respectful, obedient, and faithful to her husband. But Israel had been none of these things. That had not changed in the generation He came to.

As for His words, He sees their asking for a sign as an indication of evil, something that an adulteress would seek. The reason for this is that in seeking a sign, there is no faith behind their request. A person of faith does not need a sign. Instead, he will believe based on the surrounding evidence and the surety of the hope he possesses.

That surety should come from past history. They had the Scriptures, which detailed all of Israel’s history as well as prophesying of its coming Messiah. All they had to do was go there to find the fulfillment of innumerable signs given in prophecy.

From that springboard, they were to accept what their eyes beheld when they looked to Him. Jesus found this lack of faithful understanding highly displeasing, and so He next says, “and not it will be given it.”

The response holds the same weight and tone as what He says in John 5 –

“You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me. 40 But you are not willing to come to Me that you may have life.” John 5:39, 40

Without directly saying it, Jesus essentially conveys the same thought now. “If you want a sign, go back and search the Scriptures. Compare My ministry to what you see. After that, have faith.” Because of this, He next says to them, “if not the sign of Jonah the prophet.”

Here, Jesus tells them just where to go to find a sign confirming He is the Messiah, meaning Scripture. “Go to Jonah and see the sign He gave. Jonah’s words speak of what will come to pass. When they are fulfilled, you will have received your sign.”

But what is the sign of Jonah? Spoiler alert: it is not what Jesus will say in the next verse. The coming statement was a confirmation of Jonah’s inescapable call upon him as a prophet. It was a surety that his words were to be spoken as the Lord instructed and that they would come to pass.

Life application: Jesus says that no sign but that of the prophet Jonah would be given. As noted in the previous commentary, Mark 8 says that no sign will be given, period. But that was based on the people seeking a “sign from heaven.” The thought is not unlike what Paul says in Romans 10 –

“But the righteousness of faith speaks in this way, ‘Do not say in your heart, “Who will ascend into heaven?”’ (that is, to bring Christ down from aboveor, ‘“Who will descend into the abyss?”’ (that is, to bring Christ up from the dead). But what does it say? ‘The word is near you, in your mouth and in your heart’ (that is, the word of faith which we preach).” Romans 10:6-8

The Jews in Mark 8 wanted to bring a sign down from heaven. The Jews in Matthew 12 are looking for something already available. Jesus expects people to use what is available, and which points to Him, to make their decision about Him, meaning Scripture.

We do not need a sign from heaven to confirm what we can deduce from the word and accept by faith. What we need to do is evaluate the word, see if it matches what we know about the world around us and our relationship with God, and then accept, by faith, that Jesus is the solution to our dilemma.

Don’t be a person looking for a sign every time you need direction in life. Be confident that the Lord has you where He wants you, that He has a good plan and a purpose for you, and that by knowing and adhering to His word, He will direct your steps according to His wisdom.

“For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe. 22 For Jews request a sign, and Greeks seek after wisdom; 23 but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, 24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.” 1 Corinthians 1:21-24

Lord God, forgive us when our faith fails. Help us to be confident that, because of Jesus, we are where we should be as we live out our lives. No matter what our station in life is, You are with us. Someday, we shall be in Your presence and have what we must now only hope for. May this hope be sufficient to carry us through each day. Amen.
