II Maccabees 3:32-40

32 So the high priest, suspecting lest the king should misconceive that some treachery had been done to Heliodorus by the Jews, offered a sacrifice for the health of the man.
33 Now as the high priest was making an atonement, the same young men in the same clothing appeared and stood beside Heliodorus, saying, Give Onias the high priest great thanks, insomuch as for his sake the Lord hath granted thee life:
34 And seeing that thou hast been scourged from heaven, declare unto all men the mighty power of God. And when they had spoken these words, they appeared no more.
35 So Heliodorus, after he had offered sacrifice unto the Lord, and made great vows unto him that had saved his life, and saluted Onias, returned with his host to the king.
36 Then testified he to all men the works of the great God, which he had seen with his eyes.
37 And when the king Heliodorus, who might be a fit man to be sent yet once again to Jerusalem, he said,
38 If thou hast any enemy or traitor, send him thither, and thou shalt receive him well scourged, if he escape with his life: for in that place, no doubt; there is an especial power of God.
39 For he that dwelleth in heaven hath his eye on that place, and defendeth it; and he beateth and destroyeth them that come to hurt it.
40 And the things concerning Heliodorus, and the keeping of the treasury, fell out on this sort.
