⁷ sn The word translated hell is “Gehenna” (γέεννα, geenna), a Greek transliteration of the Hebrew words ge hinnom (“Valley of Hinnom”). This was the valley along the south side of Jerusalem. In OT times it was used for human sacrifices to the pagan god Molech (cf. Jer 7:31; 19:5-6; 32:35), and it came to be used as a place where human excrement and rubbish were disposed of and burned. In the intertestamental period, it came to be used symbolically as the place of divine punishment (cf. 1 En. 27:2, 90:26; 4 Ezra 7:36).

⁴ sn “Mountain” in English generally denotes a higher elevation than it often does in reference to places in Palestine. The Mount of Olives is really a ridge running north to south about 3 kilometers (1.8 miles) long, east of Jerusalem across the Kidron Valley. Its central elevation is about 30 meters (100 ft) higher than Jerusalem. It was named for the large number of olive trees which grew on it.
