It sounds like you might be asking about something called a “novena.” The origin of the term is Latin for “nine.”
Novena refers to the Roman Catholic practice of praying a prayer for nine days (or compressing the time frame to one day on which a prayer is prayed nine times). Such prayers are often addressed to the saints.
The Bible tells us to pray only to God, of course. And, while we are to be persistent in prayer (Matthew 7:7-11; Luke 18:1; 1 Thessalonians 5:17), Jesus tells us not to think that the wordiness of our prayers is going to impress him (Matthew 6:7-8). As Christians, we want to remember that prayer is powerful (James 5:16) because of the One receiving the prayers not the person praying.
