IV Maccabees 12:4

4 Thou seest the end of the madness of thy brethren: for they have died in torture through disobedience; and you, if disobedient, having been miserably tormented, will yourself perish prematurely.

IV Maccabees 12:4 In-Context

2 whom the tyrant pitying, though he had been dreadfully reproached by his brethren,
3 seeing him already encompassed with chains, had him brought nearer, and endeavoured to counsel him, saying,
4 Thou seest the end of the madness of thy brethren: for they have died in torture through disobedience; and you, if disobedient, having been miserably tormented, will yourself perish prematurely.
5 But if you obey, you shall be my friend, and have a charge over the affairs of the kingdom.
6 And having thus exhorted him, he sent for the mother of the boy; that, by condoling with her for the loss of so many sons, he might incline her, through the hope of safety, to render the survivor obedient.
