God gives Satan permission to strike Job physically, saying, "Behold, he is in your hand" (Job 2:6). But God sets a boundary: "Only spare his life" (Job 2:6).
In Job 2:4–6 Satan answers Yahweh by claiming that a person will surrender anything to preserve his own life. He then presses for a harsher test: not just loss of possessions and family, but direct harm to Job’s body. Satan predicts that if Job’s “bone and flesh” are struck, Job will openly reject Yahweh. These verses sit in the prologue’s second heavenly scene, following the first round of disasters in chapter 1 and Job’s initial refusal to blame God. Yahweh again points to Job’s integrity and notes that Job held fast even after intense loss.
Job 2:4–6 presents a second round of testing that moves from loss of possessions and family (chapter 1) to direct bodily suffering. Satan argues that Job’s earlier endurance can be explained by self-preservation: people will sacrifice “all that a man has” to save his own life. The text also clearly shows limits.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Job 2:6, then read the surrounding section so the answer stays connected to the passage's flow.
6Yahweh said to Satan, "Behold, he is in your hand. Only spare his life."
