What Does Exodus 9:20 Mean?

Then whoever feared the word of the LORD among the servants of Pharaoh hurried his servants and his livestock into the houses. The response to the hail warning divides Egypt into two groups: those who fear the word of the LORD (verse 20) and those who do not take it seriously (verse 21).

The "feared the word of the LORD" is the defining phrase: after six plagues, some Egyptians have become God-fearers:not covenant members, not worshippers of YHWH, but people who take YHWH's demonstrated power seriously enough to act on his word. The hail warning is the first plague preface that produces a visible behavioral response within the Egyptian population.

The God-fearers of verse 20 are Pharaoh's own servants:administrative and household officials who have watched six plagues occur exactly as predicted, who heard the gnat-confession of "the finger of God" from the magicians, and who drew the rational conclusion: when Moses says hail is coming tomorrow, it is coming tomorrow. Their fear of the word is the appropriate response to the evidence they have accumulated over the plague sequence. They do not convert to Israel's covenant; they simply conclude that YHWH's word is reliable enough to act on when it concerns their survival.

The God-fearers among Pharaoh's servants are a preview of the pattern that will recur after the Exodus: the mixed multitude that goes out with Israel (Exodus 12:38), Rahab who hid the spies (Joshua 2), the Gibeonites who sought covenant because of the Exodus report (Joshua 9). The knowledge of YHWH's acts produces a response among some Gentiles that is not full-covenant faith but is enough to align them with YHWH's people for protection. The hail-warning God-fearers are the first documented example of Gentiles choosing to trust YHWH's word rather than Pharaoh's dismissal of it.
