LXX Gen 24:14

καὶ ἔσται ἡ παρθένος ἧ ἄν ἐγὼ εἴπω Ἐπίκλινον τὴν ὑδρίαν σου ἵνα πίω, καὶ εἴπῃ μοι Πίε σύ, καὶ τὰς καμήουστ σου ποτιῶ ἕως ἄν παύσωνται πίνουσαι, ταύτην ἡτοίμασας τῷ παιδί σου Ἰσαάκ· καὶ ἐν τούτῳ γνώσομαι ὅτι ἐποίησας ἔλεος τῷ κυρίῳ μου Ἀβραίμ.

Now may it happen that the girl to whom I say, ‘Please let down your jar that I may drink,’ and who responds, ‘Drink, and I will water your camels as well’—let her be the one You have appointed for Your servant Isaac. By this I will know that You have shown kindness to my master.”
