To hurry away, to flee in alarm or trembling haste. This word describes the panicked flight driven by God's intervention — when enemies scatter, when mountains tremble, when nations flee before the Lord's presence. It also describes the haste of the Passover departure from Egypt.
Chaphaz reveals two sides of God's power: for His enemies, it means terrified flight; for His people, it means urgent deliverance. The Israelites ate the first Passover in haste (chaphaz) because God was acting swiftly to save. The Psalmist uses it to describe mountains trembling and enemies fleeing — the same God who causes panic in the wicked brings swift rescue to the righteous.
