Abisai, of Hebrew origin, means "my father is mighty." It is an uncommon name, derived from the biblical figure of the same name who was one of King David's warriors and a cousin to Joab. In the Old Testament, Abisai is known for his bravery in battle and fierce loyalty to King David. The name has been used sparingly throughout history but has seen some recent popularity as parents seek unique yet meaningful names for their children.
"The name Abisai experienced varied popularity over time, peaking with 46 births each in 2004 and 2006, but has since seen a decline, with only 24 births recorded in 2023."
