Sirach 39:30
Ben Sira, Ecclesiasticus28 "There are winds created for vengeance, and in their anger they can dislodge mountains; on the day of reckoning they will pour out their strength and calm the anger of their Maker. 29 Fire and hail and famine and pestilence, all these have been created for vengeance; 30 the fangs of wild animals and scorpions and vipers, and the sword that punishes the ungodly with destruction. 31 They take delight in doing his bidding, always ready for his service on earth; and when their time comes they never disobey his command." 32 So from the beginning I have been convinced of all this and have thought it out and left it in writing: 33 All the works of the Lord are good, and he will supply every need in its time. 34 No one can say, "This is not as good as that," for everything proves good in its appointed time.
Revelation 9:3
1 Then the fifth angel blew his trumpet, and I saw a star that had fallen from the sky to the earth, and he was given the key to the shaft of the abyss. 2 He opened the shaft of the abyss and smoke rose out of it like smoke from a giant furnace. The sun and the air were darkened with smoke from the shaft. 3 Then out of the smoke came locusts onto the earth, and they were given power like that of the scorpions of the earth. 4 They were told not to damage the grass of the earth, or any green plant or tree, but only those people who did not have the seal of God on their forehead. 5 The locusts were not given permission to kill them, but only to torture them for five months, and their torture was like that of a scorpion when it stings a person.
Notes and References
"... It is likely that the pairing of snakes and scorpions is based upon Deuteronomy 8:15 (the only place in the Old Testament where this pairing occurs; but compare Sirach 39:30), but this is not quite certain because there is evidence that the pairing developed into a fixed expression in Jewish tradition, perhaps coming originally from the use in Deuteronomy, but ultimately quite losing its allusive quality (see texts cited by Miyoshi, Anfang, 103-5, who, emphasizing the discussion of the Deuteronomy text in the early rabbinic tradition, is more confident than I can be of the allusion; note the juxtaposition in Luke 11:11-12). On the danger posed by snakes, compare Numbers 21:6-9; Sirach 21:2; for scorpions, compare 1 Kings 12:11, 14; Sirach 39:30 ... The links between Luke 10:19 and Revelation 9:3-4 have been drawn attention to by Boismard. The texts share the idea of the giving of authority, the mention of scorpions, and a reference to not harming. Perhaps nothing more can be made of the link than to suggest that in both cases we are dealing with imagery influenced by apocalyptic thought in which the final power conflict between the forces of good and of evil is in view ..."
