The Hebrew chozeq appears most prominently in Exodus to describe God's mighty hand that brought Israel out of Egypt. Exodus 13:3 commands Israel to remember the day they came out of Egypt 'with a mighty hand (chozeq yad).' The Passover and Exodus memory was meant to be carried through all generations as testimony to this strength.
The phrase chozeq yad (strength of hand / mighty hand) is central to Exodus theology. God's hand being strong meant his covenantal commitment was active and effective. When the Passover is celebrated and parents explain it to children (Exodus 13:14-16), the chozeq is the reason β 'by the strength of his hand the LORD brought us out of Egypt.' This word is the anchor of liberation theology in the OT: deliverance comes not by human force but by divine chozeq.
