‘And many of those who sleep in the ground of dust will awake, some to everlasting life, and some to shame and everlasting contempt.'
This occurs ‘at that time'. While this clearly teaches bodily resurrection, its main emphasis is on the ‘many'. Daniel may have specifically had in mind those who have been going through the time of trouble and will be delivered from a martyr's death by resurrection. They have been laid in the dusty ground, but they will arise. However, it would also include those who had died in other ways (compare Daniel 12:13). It was a hope offered to the righteous. Death was not the end. Compare also Isaiah 26:19.
But an alternative is to see Daniel as meaning rather that ‘many' (always an indefinite number in Daniel) will arise. That is that the resurrected will be a huge number. Those who awake will be many and not few. They include the multitude that no man can number out of all nations (Revelation 7:9).
But others would rise only to face shame and everlasting contempt, their bodies cast onto the burning rubbish dump outside the walls of Jerusalem, their bodies ever being eaten by maggots and burned in shame (Isaiah 66:24). The contrast was between the faithful and the unfaithful, those who knew their God (Daniel 11:32), and those who did not. As always they were not all Israel, who were Israel (compare Isaiah 49:5-6). Being a member of the true Israel meant a genuine submission to God through the covenant.
‘Shame and everlasting contempt.' The root idea is not of physical suffering. Rather the idea is that, having been raised and judged, they will be shamed and punished as described in Isaiah 66:24, their bodies lying in the valley of Hinnom, everlastingly a symbol of the consequences of sin, with no way by which their shame can be removed. Jesus gave His seal of approval to the advancement of this idea into an other-worldly Gehenna where the wicked would be finally punished (Mark 9:47-48).
We should note that both Isaiah and Daniel thought in terms of resurrection back to earth in the coming everlasting age. The idea of life in a heavenly realm was not then mooted. But Jesus added to it when He made clear that the resurrection of the righteous and the unrighteous would take men into another ‘world' to which this pointed, where they would be eternally in, or excluded from, God's presence.
‘Who sleep.' Death is likened to sleep from which a man will again awake as one raised from the dead to face his judgment.
‘The ground made of dust.' The phrase is not exactly the same as in Genesis 2:7, although similar roots are used. It was also to the dust that man was consigned when he fell (Genesis 3:19). Here is the reversal of that process, the reversal of the curse. Man lives again as ‘a new creation'. The fall has been reversed. Man (adam) will again rise from the ground (adamah).
