The Hebrew noun yesha means salvation, deliverance, or rescue from danger. It is closely related to yeshuah (H3444) and the name Yeshua (Jesus, H3091) — all sharing the root yasha (H3467), meaning 'to save.' Yesha emphasizes the outcome of salvation — safety, freedom, and restoration — rather than just the act.
Yesha connects the Old Testament's theology of deliverance directly to the person of Jesus. The name 'Jesus' in Hebrew is Yeshua — 'YHWH saves.' Isaiah is saturated with yesha-language, especially in chapters 40–66. When Simeon held the infant Jesus and said 'my eyes have seen your salvation' (Luke 2:30), he was saying in Greek what yesha says in Hebrew: God's rescue, made flesh.
