The Hebrew name Azaryah (also spelled Azariah) combines azar (H5826, to help, support) with Yah (YHWH), meaning 'YHWH has helped.' It is one of the most common personal names in the Hebrew Bible, borne by over twenty distinct individuals, including a king of Judah (also called Uzziah), a high priest, one of Daniel's three companions (also called Abednego), and multiple Levites and priests. The name is a testimony to divine help experienced and proclaimed.
The frequency of the name Azaryah in Scripture is itself theologically significant: generation after generation, parents named their children after the help of YHWH — a living testimony embedded in a person's identity. For Daniel's companion Azariah (Daniel 3), the name was prophetically apt: he walked through fire and the LORD helped. The New Testament parallel is boetheia (G996, help) and parakletos (G3875, helper/advocate). God's help is the foundation of faith.
