Revelation 17:9
Context17:9 (This requires 6 a mind that has wisdom.) The seven heads are seven mountains 7 the woman sits on. They are also seven kings:


[14:12] 2 tn Or “the perseverance.”
[14:12] 4 tn The words “hold to” are implied as a repetition of the participle translated “keep” (οἱ τηροῦντες, Joi throunte").
[14:12] 5 tn Grk “faith of Jesus.” The construction may mean either “faith in Jesus” or “faithful to Jesus.” Either translation implies that ᾿Ιησοῦ (Ihsou) is to be taken as an objective genitive; the difference is more lexical than grammatical because πίστις (pistis) can mean either “faith” or “faithfulness.”
[17:9] 6 tn Grk “Here is the mind that has wisdom.”
[17:9] 7 tn It is important to note that the height of “mountains” versus “hills” or other topographical terms is somewhat relative. In terms of Palestinian topography, Mount Tabor (traditionally regarded as the mount of transfiguration) is some 1,800 ft (550 m) above sea level, while the Mount of Olives is only some 100 ft (30 m) higher than Jerusalem.
