3 καὶ ὤφθη ἄγγελος Κυρίου πρὸς τὴν γυναῖκα καὶ εἶπεν πρὸς αὐτήν Ἰδοὺ σὺ στεῖρα καὶ οὐ τέτοκας, καὶ συλλήμψῃ υἱόν.
4 καὶ νῦν φύλαξαι δὴ καὶ μὴ πίῃς οἶνον καὶ μέθυσμα, καὶ μὴ φάγῃς πᾶν ἀκάθαρτον
5 ὅτι ἰδοὺ σὺ ἐν γαστρὶ ἔχεις καὶ τέξῃ υἱόν, καὶ σίδηρος οὐκ ἀναβήσεται ἐπὶ τὴν κεφαλὴν αὐτοῦ, ὅτι ναζεὶρ θεοῦ ἔσται τὸ παιδάριον ἀπὸ τῆς κοιλίας· καὶ αὐτὸς ἄρξεται τοῦ σῶσαι τὸν Ἰσραὴλ ἐκ χειρὸς Φυλιστιείμ.
6 καὶ εἰσῆλθεν ἡ γυνὴ καὶ εἶπεν τῷ ἀνδρὶ αὐτῆς λέγουσα Ἄνθρωπος θεοῦ ἦλθεν πρὸς μέ, καὶ εἶδος αὐτοῦ ὡς εἶδος ἀγγέλου θεοῦ φοβερὸν σφόδρα· καὶ οὐκ ἠρώτησα αὐτὸν πόθεν ἐστίν, καὶ τὸ ὄνομα αὐτοῦ οὐκ ἀπήγγειλέν μοι.
7 καὶ εἶπέν μοι Ἰδοὺ σὺ ἐν γαστρὶ ἔχεις καὶ τέξῃ υἱόν· καὶ νῦν μὴ πίῃς οἶνον καὶ μέθυσμα, καὶ μὴ φάγῃς πᾶν ἀκάθαρτον, ὅτι ἅγιον θεοῦ ἔσται τὸ παιδάριον ἀπὸ γαστρὸς ἕως ἡμέρας θανάτου αὐτοῦ.
14 διὰ τοῦτο δώσει Κύριος αὐτὸς ὑμῖν σημεῖον· ἰδοὺ ἡ παρθένος ἐν γαστρὶ λήμψεται καὶ τέξεται υἱόν, καὶ καλέσεις τὸ ὄνομα αὐτοῦ Ἐμμανουήλ

This is about John the Baptist, JtB for intimi, Johannes the Immerser for those who take it literally
As you can see, there is verbatim agreement between Isaiah and Luke (the yellow), and "inspiration" in the rest. The colours are pairs, and Judges 3:13 uses the verb that Isaiah uses; it is fair to say that either Judges also draws on Isaiah or vice versa, or that these words are just very common and prone to occur in this context in the same order, or a bit of both perhaps.
In bold the words that are verbatim, in bold italics those that inspired
Basically the entire Samson birth story is this, and what I haven't highlighted is pretty much a repetition from what I have done so.
The story continues there but the man just wants to make certain, the angel appears again, repeats itself, etc. But... it ends with
and Luke ends with
Inspiration again, so going out on a limb. Different verb for grow, same scenery. "Blessed by the Lord" changes to "strengthened in spirit". And both last verses tell everything about the continuation of the story, designating the destination / location
Now, onto Jesus:

A double whammy there, with Luke being verbatim to Isaiah AND Judges, even using the verb of Judges that includes the prefix
