v1-10: Job curses the day of his birth. Had he not been born, he would not have experienced his current suffering. The past joys of his life are forgotten in his painful circumstance.
'God allowed Job to rant at him. ... When we cry and shout at God like an angry, frightened, toddler, he doesn't retaliate in anger, but wraps us in his arms and accepts a beating from our tiny fists until we calm down and receive his comfort.' (David Instone-Brewer, quoted in Christianity magazine, Dec 2018).
v11-19: Job thinks he would have found relief in death, such was his current pain.
His life has brought him into trial and turmoil; in death he would be lying down in peace, asleep and at rest.
There is an equality in death; kings and counsellors and rulers are all at rest; slaves and masters, the wicked, stillborn children; all human distinctions are finished.
v20-22: The light of life continues, even to Job in his misery and bitterness of soul. Here is Job's expression of sorrow; 'Would not death have been better?'
v23-24: Job has received life, but now his experience was little more than existence.
v25: It is not clear what Job feared; perhaps physical pain, perhaps material poverty; Does God send what we fear in order to teach us a lesson, and to build faith and character?
v26: No peace, no quietness, no rest; a life of sorrow and trouble. Eliphaz later commented (5.7) that such things are our normal experience.
