LXX Gen 29:10

ἐγένετο δὲ ὡς ἴδεν Ἰακὼβ τὴν Ῥαχὴλ θυγατέρα Λαβὰν ἀδελφοῦ τῆς μητρὸς αὐτοῦ, καὶ προσελθὼν Ἰακὼβ ἀπεκύλισεν τὸν λίθον ἀπὸ τοῦ στόματος τοῦ φρέατος, καὶ ἐπότισεν τὰ πρόβατα λαβὰν τοῦ ἀδελφοῦ τῆς μητρὸς αὐτοῦ.

As soon as Jacob saw Rachel, the daughter of his mother’s brother Laban, with Laban’s sheep, he went up and rolled the stone away from the mouth of the well and watered his uncle’s sheep.
