Charles Spurgeon Commentary Exodus 14:6-8

"And he made ready his chariot, and took his people with him: and he took six hundred chosen chariots, and all the chariots of Egypt, and captains over all of them. And Jehovah hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel: for the children of Israel went out with a high hand." — Exodus 14:6-8 (ASV)

They were resolute and brave as long as they realized that God was with them; and the Egyptians behind them were bold and proud although God was not with them. There were two high hands that day, the high hand of the proud, puny Pharaoh and the high hand of the ever-blessed omnipotent Jehovah.
