The Hebrew chadal means to stop, to cease, to desist, or to refrain from action. It can describe a person stopping an activity, God restraining His hand, or something coming to an end.
Chadal appears powerfully in Exodus 14:12 when the Israelites beg Moses to let them alone in Egypt, and in Isaiah 1:16 where God commands, 'stop doing wrong.' The verb also describes the ceasing of Israel's manna (Joshua 5:12) and the silence that fell at the Red Sea crossing. Theologically, chadal presents the sovereign freedom of God to start or stop what He wills, and calls human beings to the discipline of knowing when to stop — when to cease striving (Psalm 46:10 uses raphah but the concept overlaps) and trust God.
