1 Samuel 1:11

1:11 She made a vow saying, “O Lord of hosts, if you will look with compassion on the suffering of your female servant, remembering me and not forgetting your servant, and give a male child to your servant, then I will dedicate him to the Lord all the days of his life. His hair will never be cut.”

1 Samuel 27:1

David Aligns Himself with the Philistines

27:1 David thought to himself, “One of these days I’m going to be swept away by the hand of Saul! There is nothing better for me than to escape to the land of the Philistines. Then Saul will despair of searching for me through all the territory of Israel and I will escape from his hand.”
