Shared ground
Exodus 4:1–7 presents a credibility crisis and God’s response. Moses expects Israel to reject his message and deny that Yahweh appeared to him (explicit in v.1). Yahweh answers by giving Moses two repeatable, public actions: the staff becomes a snake and returns to a staff, and Moses’ hand becomes diseased-looking and then returns to normal (explicit in vv.2–7). These are not only wonders; the text states their purpose: “that they may believe” Yahweh appeared to Moses and is the God of the ancestors named (explicit in v.5).
The passage also emphasizes that God works through ordinary objects and human agency. Yahweh starts with what is in Moses’ hand (v.2), gives commands, and Moses performs them step by step (vv.3–4, 6–7). Moses’ fear and hesitation are not hidden; they are part of the scene (v.3).
Where interpretation differs (only where needed)
Who are “they” meant to believe? The most direct reading is that “they” refers to the Israelites Moses has in mind in v.1, since he just said “they will not believe me.” Others think the signs are also preparing Moses for later confrontations, so the immediate target is Israel but the broader narrative effect includes Egypt’s leadership as well.
What exactly is the “leprous” hand? The text describes a sudden, alarming change “as white as snow” and then immediate restoration (vv.6–7). Some readers treat this as a specific medical disease; others argue it is primarily a visual description of a frightening skin condition (with strong social impact), without requiring a precise diagnosis.
Why the disagreement exists
The passage uses pronouns (“they”) without re-naming the group, so readers decide whether to keep the focus narrow (Israel in vv.1–5) or widen it based on the larger story. Also, “leprous” is a traditional English rendering for an ancient term that can cover more than one skin condition; the narrative focuses on appearance and reversal rather than medical detail.
What this passage clearly contributes
It shows that God addresses doubts about divine commissioning with observable signs, not only spoken claims (vv.2–7). It frames Moses’ mission as rooted in the God of Abraham, Isaac, and Jacob (v.5), linking the coming deliverance to ancestral identity and continuity. It also introduces a pattern that will recur in Exodus: God’s power is displayed in ways that can be seen, and those displays are aimed at producing belief about who Yahweh is and what he is doing Exodus 4:1–7.
