Mark 9:43 uses the same 'cut it off' logic for the hand — reinforcing the radical amputation of anything causing sin to avoid hell.

In Genesis 3:6, Eve's eye saw the fruit and led to sin—this pattern of the eye as the gateway to temptation underlies Jesus' radical command to pluck out the eye.

Job 31:1 shows Job making a covenant with his eyes to avoid lust—parallel to Jesus' call to cut off what causes sin through the eye.

Matthew 5:28 reveals that looking with lust is adultery of the heart—the same teaching on the eye's role in sin that Jesus then applies with amputation.

Matthew 5:29 is the parallel passage—Jesus gives the identical instruction to gouge out the eye that causes sin, directly echoing Mark.

Galatians 4:15 recalls the Galatians' willingness to tear out their eyes for Paul—a literal echo of Jesus' language, applied to devotion.

Psalm 119:37 prays for God to turn eyes from worthless things—a similar principle of guarding the eye from sin, though less radical.
