God is salvation
Joshau is a rare variant of the Hebrew name Joshua. It derives from the Hebrew name Yehoshua, which combines the name of God with a root meaning to deliver or save. While Joshua is a perennial classic, this specific spelling is often considered a modern variation or a phonetic transcription error that has gained independent use.
