Markus 9:43

9:43 If your hand causes you to sin, cut it off! It is better for you to enter into life crippled than to have ¹  two hands and go into hell, ²  to the unquenchable fire.

Markus 9:48

9:48 where their worm never dies and the fire is never quenched.

[9:43]  ¹ tn Grk “than having.”

[9:43]  ² 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). This Greek term also occurs in vv. 45, 47.
