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 9:18

9:18 Whenever it seizes him, it throws him down, and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, but ³  they were not able to do so.” ⁴ 

[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.

[9:18]  ³ tn Here καί (kai) has been translated as “but” to indicate the contrast present in this context.

[9:18]  ⁴ tn The words “to do so” are not in the Greek text, but have been supplied for clarity and stylistic reasons.
