Shezab is the Aramaic equivalent of the Hebrew natsal (deliver/rescue), appearing 5 times in the book of Daniel in the context of miraculous divine deliverance. It is the word used by Daniel's three friends — Shadrach, Meshach, and Abednego — and by King Darius concerning Daniel's deliverance from the lions' den. As an Aramaic term, it places Israel's God's power for salvation within the universal language of the ancient Near East.
The theology of shezab is bold confessional faith. In Daniel 3:17, the three young men declare: 'our God whom we serve is able to deliver [shezab] us from the burning fiery furnace.' Remarkably, they add in verse 18: 'But if not, be it known to you, O king, that we will not serve your gods.' This is faith unconditioned by outcome — the theology of Hebrews 11's 'hall of faith' where some were delivered and some were not, but all died in faith. Shezab anchors miraculous deliverance in God's character and sovereignty, not in human circumstances.
