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 25:34

25:34 Otherwise, as surely as the Lord, the God of Israel, lives – he who has prevented me from harming you – if you had not come so quickly to meet me, by morning’s light not even one male belonging to Nabal would have remained alive!”
