The name יֵשׁוּעַ, Yeshua (transliterated in the English Old Testament as Jeshua), is a late form of the Biblical Hebrew name יְהוֹשֻׁעַ, Yehoshua (Joshua), and spelled with a waw in the second syllable.
Yeshua in Hebrew is a verbal derivative from "to rescue", "to deliver". Among the Jews of the Second Temple period, the Biblical Aramaic/Hebrew name יֵשׁוּעַ, Yēšūaʿ was common: the Hebrew Bible mentions several individuals with this name – while also using their full name Joshua. This name is a feature of biblical books written in the post-Exilic period (Ezra, Nehemiah, and Chronicles) and was found in the Dead Sea Scrolls, though Haggai and Zechariah prefer the spelling Joshua. Strong's Concordance connects the name יֵשׁוּעַ, Yēšūaʿ, in the English form Jeshua (as used in multiple instances in Ezra, Nehemiah, and 1 and 2 Chronicles), with the verb "to deliver" (or, "to rescue"). It is often translated as "He saves," to conform with Matthew 1:21: "She will bear a Son; and you shall call His name Jesus (in Greek Iesous, in Latin Iesus), for He will save His people from their sins".
The name ישוע occurs in the Hebrew of the Old Testament at verses Ezra 2:2, 2:6, 2:36, 2:40, 3:2, 3:8, 3:9, 3:10, 3:18, 4:3, 8:33; Nehemiah 3:19, 7:7, 7:11, 7:39, 7:43, 8:7, 8:17, 9:4, 9:5, 11:26, 12:1, 12:7, 12:8, 12:10, 12:24, 12:26; 1 Chronicles 24:11; and 2 Chronicles 31:15, and also in Aramaic at Ezra 5:2. In Nehemiah 8:17 this name refers to Joshua son of Nun, the successor of Moses, as leader of the Israelites. In earlier English (where adaptations of names of Biblical figures were generally based on the Latin Vulgate forms), Yeshua was generally transcribed identically to "Jesus" in English.
See this spelling in Hebrews 4:8, a clear reference to Joshua but spelt as Jesus in the King James Version.
