Job 20:22 describes distress overtaking the wicked in their plenty — directly opposing Job 21:23's claim that they die in ease.

Job 20:23 says God's anger rains down on the wicked when they are full — contrasting Job 21:23's picture of peaceful death.

In Job 36:14, the wicked die young among cult prostitutes — contrasting the full vigor death here.

Psalm 73:4 says the wicked have no pangs until death — a direct parallel to Job 21:23's 'full vigor' and ease.

Psalm 73:5 states the wicked are not troubled like others — mirroring Job 21:23's description of a secure, untroubled death.

Luke 12:19-21 tells of a rich fool who dies suddenly while secure — parallel to Job 21:23's ease, but with a warning of judgment.
