"Adonai" is a Hebrew word that means "my Lord" and is often used in Jewish prayers and texts to refer to God. It is a title of respect and reverence, emphasizing the authority and sovereignty of God in the lives of believers. In the context of the Hebrew Bible, "Adonai" is frequently used as a substitute for the sacred name of YHWH, which is considered too holy to be spoken aloud. This practice reflects the deep respect for the divine name and the importance of maintaining a relationship with God through prayer and worship.
