LXX 2 Macc 4:34

ὅθεν ὁ Μενέλαος λαβὼν ἰδίᾳ τὸν Ἀνδρόνικον, παρεκάλει χειρώσασθαι τὸν Ὀνίαν· ὁ δὲ παραγενόμενος ἐπὶ τὸν Ὀνίαν καὶ πεισθεὶς ἐπὶ δόλῳ καὶ δεξιασθεὶς μεθʼ ὅρκων, δοὺς δεξιάν, καίπερ ἐν ὑποψίᾳ κείμενος, ἔπεισεν ἐκ τοῦ ἀσύλου προελθεῖν· ὃν καὶ παραχρῆμα παρέκλεισεν, οὐκ αἰδεσθεὶς τὸ δίκαιον.

Whereupon Menelaus coming to Andronicus, desired him to kill Onias. And he went to Onias, and gave him his right hand with an oath, and (though he were suspected by him) persuaded him to come forth out of the sanctuary, and immediately slew him, without any regard to justice.
