What does Exodus 9:21 mean?
God has repeatedly commanded Pharaoh to release the Hebrew slaves (Exodus 5:1; 7:16; 8:1, 21; 9:1). Pharaoh has repeatedly refused (Exodus 5:2; 7:13–14, 22; 8:15, 19, 32; 9:7). As a result, Egypt suffered numerous disasters (Exodus 7:21; 8:6, 17, 24; 9:6, 10). These are clearly divine (Exodus 8:19) and meant to prove the power of the Israelite God. Moses announces the threat of a seventh plague (Exodus 9:18), but also advice. Those who take shelter can avoid losing animals and servants (Exodus 9:19). Some of the Egyptians wisely chose to follow this guidance (Exodus 9:20), but some do not. Those who refuse to "fear" God (Proverbs 1:7) even now will suffer great losses (Exodus 9:22–26).The phrase "the word of the Lord" is significant. Though a common expression in the Old Testament, the phrase only appears twice in the book of Exodus. Both are in this passage (Exodus 9:20). The book of Genesis uses this phrase only twice, as well, when God explains His covenant to Abraham (Genesis 15:1, 4). Later books make more use of the expression as they record the laws given to Israel. The term is often tied to warnings about disobedience (Numbers 3:16, 51; 15:31; 24:13; 36:5, Deuteronomy 5:5; 34:5).
