LXX Gen 42:34

καὶ ἀγάγετε πρὸς με τὸν ἀδελφὸν ὑμῶν τὸν νεώτερον, καὶ γνώσομαι ὅτι οὐ κατάσκοποί ἐστε, ἀλλ’ ὅτι εἰρηνικοί ἐστε· καὶ τὸν ἀδελφὸν ὑμῶν ἀποδώσω ὑμῖν, καὶ τῆ γῇ ἐμπορεύεσθε.

But bring your youngest brother back to me so I will know that you are not spies but honest men. Then I will give your brother back to you, and you can trade in the land.’”
