LXX Gen 42:7

ἰδὼν δὲ ἸωσὴΦ τοὺς ἀδελφοὺς αὐτοῦ ἐπέγνω, καὶ ἠλλοτριοῦτο ἀπ’ αὐτῶν καὶ ἐλάλησεν αὐτοῖς σκληρά, καὶ εἶπεν αὐτοῖς ΙΙόθεν ἥκατε ; οἱ δὲ εἶπαν Ἐκ γῆς Χανάαν, ἀγοράσαι βρώματα.

And when Joseph saw his brothers, he recognized them, but he treated them as strangers and spoke harshly to them. “Where have you come from?” he asked. “From the land of Canaan,” they replied. “We are here to buy food.”
