Salvation
Johsua is a rare spelling variant of the Hebrew name Joshua (Yehoshua). It shares the same etymological roots, signifying that the divine is a source of deliverance. While Joshua is a perennial favorite, this specific transposition of letters is often considered a modern variation or a common misspelling.
