LXX 2 Macc 9:5

ὁ δὲ παντεπόπτης κύριος ὁ θεὸς τοῦ Ἰσραὴλ ἐπάταξεν αὐτὸν ἀνιάτῳ καὶ ἀοράτῳ πληγῇ· ἄρτι δὲ αὐτοῦ καταλήξαντος τὸν λόγον, ἔλαβεν αὐτὸν ἀνήκεστος τῶν σπλάγχνων ἀλγηδὼν καὶ πικραὶ τῶν ἔνδον βάσανοι,

But the Lord, the God of Israel, that seeth all things, struck him with an incurable and an invisible plague. For as soon as he had ended these words, a dreadful pain in his bowels came upon him, and bitter torments of the inner parts.
