II Maccabees 4:34

34 Wherefore Menelaus, taking Andronicus apart, prayed, him to get Onias into his hands; who being persuaded thereunto, and coming to Onias in deceit, gave him his right hand with oaths; and though he were suspected by him, yet persuaded he him to come forth of the sanctuary: whom forthwith he shut up without regard of justice.

II Maccabees 4:34 In-Context

32 Now Menelaus, supposing that he had gotten a convenient time, stole certain vessels of gold out of the temple, and gave some of them to Andronicus, and some he sold into Tyrus and the cities round about.
33 Which when Onias knew of a surety, he reproved him, and withdrew himself into a sanctuary at Daphne, that lieth by Antiochia.
34 Wherefore Menelaus, taking Andronicus apart, prayed, him to get Onias into his hands; who being persuaded thereunto, and coming to Onias in deceit, gave him his right hand with oaths; and though he were suspected by him, yet persuaded he him to come forth of the sanctuary: whom forthwith he shut up without regard of justice.
35 For the which cause not only the Jews, but many also of other nations, took great indignation, and were much grieved for the unjust murder of the man.
36 And when the king was come again from the places about Cilicia, the Jews that were in the city, and certain of the Greeks that abhorred the fact also, complained because Onias was slain without cause.
