Josuah is of Hebrew origin, derived from the name Yisrael, meaning 'God will save.' It was borne by Joshua, a significant figure in the Old Testament, who succeeded Moses as leader of the Israelites and conquered the Promised Land.
"Josuah is a somewhat uncommon name, with fluctuations in its popularity over the years. The highest number of births was recorded in 1978 and 1991, each with 7 babies named Josuah. However, it seems that this name's usage has waned since 2004, with only one more birth recorded after a gap of 13 years."
