Hannah prayed:

My heart rejoices in the Lord;
my horn is lifted up by the Lord.
My mouth boasts over my enemies,
because I rejoice in Your salvation.

Those who oppose the Lord will be shattered;
He will thunder in the heavens against them.
The Lord will judge the ends of the earth.
He will give power to His king;
He will lift up the horn of His anointed.

Jonathan attacked the Philistine garrison that was in Geba, and the Philistines heard about it. So Saul blew the ram’s horn throughout the land saying, “Let the Hebrews hear!”

The Lord said to Samuel, “How long are you going to mourn for Saul, since I have rejected him as king over Israel? Fill your horn with oil and go. I am sending you to Jesse of Bethlehem because I have selected a king from his sons.”

So Samuel took the horn of oil, anointed him in the presence of his brothers, and the Spirit of the Lord took control of David from that day forward. Then Samuel set out and went to Ramah.
