τῇδε occurs only once in the GNT, here in the phrase τῇδε ἦν ἀδελφὴ "to her there was a sister" = "she had a sister". τάδε occurs twice in Acts, 7 times in the Revelation, τήνδε once in James, for a total of 11 occurrences in the GNT.Luke 10:39 wrote:καὶ τῇδε ἦν ἀδελφὴ καλουμένη Μαριάμ
It seems to be much more common in Septuagint Greek, and this usage is similar to sentences like these, especially the first two:
Gn 25:24 καὶ ἐπληρώθησαν αἱ ἡμέραι τοῦ τεκεῖν αὐτήν καὶ τῇδε ἦν δίδυμα ἐν τῇ κοιλίᾳ αὐτῆς
Gn 38:27 ἐγένετο δὲ ἡνίκα ἔτικτεν καὶ τῇδε ἦν δίδυμα ἐν τῇ γαστρὶ αὐτῆς
2Mc 6:12 παρακαλῶ οὖν τοὺς ἐντυγχάνοντας τῇδε τῇ βίβλῳ μὴ συστέλλεσθαι διὰ τὰς συμφοράς λογίζεσθαι δὲ τὰς τιμωρίας μὴ πρὸς ὄλεθρον ἀλλὰ πρὸς παιδείαν τοῦ γένους ἡμῶν εἶναι
I found a lot of occurrences of τῇδε in classical sources, but found τῇδε ἦν only in Josephus (I don't have TLG, so this is not an exhaustive search):
What kind of Greek is τῇδε ἦν ἀδελφὴ? Is it fair to say this is a usage influenced by the Septuagint?Flavius Josephus. Antiquities of the Jews, Book 18 section 38 wrote:γῆς ἐπιδόσει, εἰδὼς παράνομον τὸν οἰκισμὸν ὄντα καὶ ἀπὸ τοῦ Ἰουδαίοις πατρίου διὰ τὸ ἐπὶ μνήμασιν, ἃ πολλὰ τῇδε ἦν, ἀνῃρημένοις τὴν ἵδρυσιν τῇ Τιβεριάδι γενέσθαι· μιαροὺς δὲ ἐπὶ ἑπτὰ ἡμέρας εἶναι τοὺς οἰκήτορας ἀγορεύει ἡμῖν
