The Sufferings Of The Righteous Under Injustice (Isaiah 57:1-2).
‘The righteous man perishes,
And no man lays it to heart,
And the men of covenant love (chesed) are taken away,
None considering that the righteous is taken away from evil (‘from the face of evil').
He enters into peace.
They rest in their beds,
Each one who walks in his uprightness.'
The sign of the total failure of the leadership of God's supposed people is that the very people whom they should have been protecting are the ones who are perishing without anyone taking any notice. He who is righteous, and walking in God's ways, perishes through injustice and communal violence, while the law ignores the situation. Those who love God and obey His covenant are being arrested and are ‘disappearing', possibly because they protest at what is happening to the true worship of Yahweh and at the false worship of multitudinous gods.
Nor do men consider the fact that this is because evil men have taken control, so that the righteous are taken away ‘from before evil'. The constant lesson of history is the apathy of the ordinary man in the face of what is going on around him. As long as it does not affect him too deeply he lets things slide, only for him to wake up when it is too late.
But Isaiah gives assurance to the righteous. Whatever happens to them externally they will find peace within themselves and peace with God. In the midst of their experiences they enter into peace. At least they can sleep at nights. Their consciences are untroubled. The thought may also include the idea of the sleep of death. Whether alive or dead they rest in Yahweh in perfect content (Psalms 16:11; Psalms 17:15; Psalms 23:6). Their beds of peace are in contrast with the beds of delusion (Isaiah 56:10) and the beds of adultery (Isaiah 57:7).
Notice the constant movement between singulars and plurals. What he describes is true of each of the righteous, and of all.
