Santo Anjo do Senhor is the Portuguese form of the Angel of God prayer, a traditional Catholic devotion asking a guardian angel to watch over, guide and protect the person praying. Generations of Portuguese speaking children learn it as one of their first prayers, usually at home or in catechism, and short recitations now circulate widely as shareable audio. This version by Simone Jaques has spread as a brief WhatsApp style clip, valued less as a performance than as a familiar blessing people can forward for comfort, faith and nightly protection.
