"I have read with all my heart, and similarly it says (1 Samuel 7:3), 'And Samuel spoke to all the house of Israel, saying, if you return to the Lord with all your hearts, then put away the foreign gods and the Ashtaroth from among you, and prepare your hearts to the Lord, and serve Him only; and He will deliver you out of the hand of the Philistines.' What does it mean to return to the Lord with all your hearts?
Rather, Samuel said, if you repent with all your hearts, then the Lord will answer my prayer that I pray for you. And similarly it says (1 Samuel 7:5), 'And Samuel said, gather all Israel to Mizpah, and I will pray to the Lord for you.' And they gathered to Mizpah and drew water. And what water did they draw and pour out?
It was that they repented and poured out their hearts like water before the Lord in complete repentance. And similarly, Jeremiah says (Lamentations 2:19), 'Pour out your heart like water before the Lord,' and so it is said (1 Samuel 7:6), 'And they drew water.' Therefore, it is said, 'I have read with all my heart.'"...
