Keluaran 14:8

14:8 But the Lord hardened the heart of Pharaoh king of Egypt, and he chased after the Israelites. Now the Israelites were going out defiantly. ¹ 

[14:8]  ¹ tn Heb “with a high hand”; the expression means “defiantly,” “boldly,” or “with confidence.” The phrase is usually used for arrogant sin and pride, the defiant fist, as it were. The image of the high hand can also mean the hand raised to deliver a blow (Job 38:15). So the narrative here builds tension between these two resolute forces.
