Eben Haezer means "stone of help" — the name Samuel gave to the memorial stone he erected after God intervened for Israel against the Philistines. It also names the battlefield where Israel was earlier defeated.
Ebenezer is one of Scripture's most powerful commemorative names. Samuel set up the stone and declared, "Thus far the LORD has helped us" (1 Samuel 7:12). This act of memorial theology was practiced throughout Israel's history: stones marked the places where God met His people. The same location that witnessed Israel's defeat (1 Samuel 4) later became the site of supernatural victory — a reminder that the God who allows discipline also brings restoration. The hymn "Come Thou Fount" draws on this word: "Here I raise mine Ebenezer."
