Hitherto hath the LORD helped us

Then Samuel took a stone, and set it between Mizpeh and Shen, and called the name of it Ebenezer, saying, Hitherto hath the LORD helped us.
(1 Samuel 7:12)

1/ What brought God's people to be so far from the Lord .
2/ A people returning to the LORD .
3/ Stirred up adversaries and the Lord's use of them to give a blessing and deliverance .
4/ A time, a place and a way to mark the LORD's help so far .
