LXX Gen 28:11

καὶ ἀπήντησεν τόπῳ καὶ ἐκοιμήθη ἐκεῖ· ἔδυ γὰρ ὁ ἥλιος· καὶ ἔλαβεν ἀπὸ τῶν λίθων τοῦ τόπου καὶ ἐπέθηκεν πρὸς κεφαλῆς αὐτοῦ, καὶ ἐκοιμήθη ἐν τῷ τόπῳ ἐκείνῳ.

On reaching a certain place, he spent the night there because the sun had set. And taking one of the stones from that place, he put it under his head and lay down to sleep.
