Luke indicated that Jesus said that just as Jonah became a sign to the people of Nineveh (καθὼς γὰρ ἐγένετο Ἰωνᾶς τοῖς Νινευείταις σημεῖον), so, too, the Son of Man will be a sign to this generation (οὕτως ἔσται καὶ ὁ Υἱὸς τοῦ ἀνθρώπου τῇ γενεᾷ ταύτῃ). This saying about the sign of Jonah can also be found in Matthew, chapter 12:39-40. Perhaps this was a Q source, going back to Hebrew scripture roots. Jesus used this story of the prophet Jonah, chapter 1:17, where he was in the belly of the whale or the sea monster for 3 days and 3 nights. The obvious comparison between the 3 days and 3 nights in the belly of the fish and Jesus in the tomb was not lost on the early Christians. Matthew was even more specific than Luke. He indicated that Jesus said that the only sign they were going to get was the sign of the prophet Jonah, who had been in the belly of the sea monster or whale that swallowed him for 3 days and 3 nights. Thus, the Son of Man would be 3 days and 3 nights in the heart of the earth. This was a clear allusion to the death of Jesus in the tomb for 3 days and 3 nights before his resurrection. Luke was not as clear or specific. What do you know about Jonah and the whale?
Luke then had Elizabeth shout out, as if speaking for the baby in her womb. Elizabeth exclaimed with a loud cry (καὶ ἀνεφώνησεν κραυγῇ μεγάλῃ). She said that Mary was blessed among all women (καὶ εἶπεν Εὐλογημένη σὺ ἐν γυναιξίν). Blessed would be the fruit of her womb (καὶ εὐλογημένος ὁ καρπὸς τῆς κοιλίας σου)! Thus, Elizabeth, without a word spoken, knew that Mary was pregnant with an important child. These words of Elizabeth then became the second part of the “Ave Maria,” prayer. “Hail Mary! Full of Grace! The Lord is with you! Blessed are you among women! Blessed is the fruit of your womb! Jesus!” Thus, Elizabeth, via Luke, is the biblical originator of this Marian prayer that became popular in the middle ages down to the present time.
This is almost word for word in Matthew, chapter 24:32, and similar in Luke, chapter 21:29-30. Mark indicated that Jesus said they were to learn a lesson or parable (μάθετε τὴν παραβολήν) about the fig tree (Ἀπὸ δὲ τῆς συκῆς). As soon as its branches or shoots became tender (ὅταν ἤδη ὁ κλάδος αὐτῆς ἁπαλὸς γένηται), it would put forth its leaves (καὶ ἐκφύῃ τὰ φύλλα). Then you would know that summer was near (γινώσκετε ὅτι ἐγγὺς τὸ θέρος ἐστίν). In other words, the early leaves on a tree indicated that summer was coming. Let’s hope that summer keeps coming.
This short saying is word for word in Luke, chapter 9:49, but not in Matthew. Mark indicated that Jesus said that whoever was not against them (ὃς γὰρ οὐκ ἔστιν καθ’ ἡμῶν), then he was for them (ὑπὲρ ἡμῶν ἐστιν). You were a friend until you became an enemy. If they were not against Jesus, then they must be for him.
This young girl Jerusalem trusted in her beauty. She played a whore or became a prostitute. Due to her beautiful fame, she lavished her gifts on any passer-by. In fact, she made colorful shrines for herself, as she played the whore or prostitute at these shrines. Nothing like this had ever been seen. Nothing like it will ever be seen again.
This section of Baruch indicates that wisdom became human in some sense, like an incarnation. Surely God, and not Yahweh, was the creator of the world. Thus no other god or person could compare with him. He had full knowledge of everything. He was omniscient. Thus he gave wisdom to his servant Jacob. He also gave wisdom to Israel, whom he loved. The use of both Jacob and Israel is interesting, since it implies that Jacob was a person and Israel was a name of all his descendants. Then there is the final intriguing comment about how she, wisdom, appeared on earth and lived with humans. Some Christians see this as a hint about the incarnation of Jesus. However, it should be noted that the reference is to a she, a female. Wisdom was generally seen as feminine, not masculine like Jesus. Finally, she has already appeared, so that this is not a future aspirational comment. Wisdom is already living among humans. You just have to find this personification of wisdom here on earth.
Sirach says that he was like a little channel from a river. He used that water to irrigate his garden and flowers. Then the channel became a river and the river became a sea. His instructions shined forth like the dawn of a new day. The brightness could be seen from a long distance away. His teaching was like prophecy for all future generations. He was not working for himself, but to give instructions to all seeking it.
