Revelation 13:5
And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months. (Revelation 13:5)

Gr. poieō, “to do,” “to perform,” “to execute.”
Power.
Gr. exousia, “authority.”
Blasphemies.
 See on v. 1; cf. v. 6, where these blasphemies are further described.
Great things.
 For examples of the boastful claims of the papacy see on Dan. 7:25. The specifications of Rev. 13:5-7 clearly identify the power symbolized by the beast with that represented by the little horn of the fourth beast of Dan. 7. Among the parallels the following may be noted:
 (1) The beast of Rev. 13 had a “mouth speaking great things and blasphemies” (v. 5); the little horn of Dan. 7 also had a “mouth speaking great things” (v. 8).
 (2) The beast was “to continue forty and two months” (Rev. 13:5; see on ch. 12:6); the horn was to continue “until a time and times and the dividing of time” (see on Dan. 7:25).
 (3) The beast was “to make war with the saints, and to overcome them” (Rev. 13:7); the horn “made war with the saints, and prevailed against them” (Dan. 7:21).
Forty and two months.
 See on ch. 12:6; cf. on ch. 11:2.
