Turn over to Exodus 9. The Bible also describes people who do not fear God. By the time Moses had brought seven different plagues upon Egypt. Pharaoh knew God well enough to fear Him, but he did not. Though Pharaoh appeared to repent, Moses replied, "I know that you still do not fear the Lord."
So even after Pharaoh allowed Israel to flee Egypt, his disobedience and later pursuing the children of Israel indicated that he still did not truly fear God, even to the point where he was killed. And to that point, he still did not fear Him. He had a terror of God, possibly, at times but not a fear. Consequently, God destroyed Pharaoh's army, just as He promised to bring judgment upon all who do not fear Him, while preserving those who do fear Him.
