Eben-ezer is a special place that is mentioned in the Bible in the Old Testament. It was a location where the Israelites (God's chosen people) were involved in a big battle against the Philistines (people who were not following God). The Israelites asked God for help and he answered by giving them strength and power to win the battle. To remember this special moment, they named the place Eben-ezer, which means "stone of help". This stone served as a reminder to the Israelites that God was always there to help them in times of need.
