🔼The name Jeriah in the Bible
Being the firstborn, Jeriah was the chief of the Hebronites and in the fortieth year of his reign, David made him and his brothers overseers of the tribes of Reuben, Gad and Manasseh, which were the tribes that lived on the east of the Jordan (1 Chronicles 26:31).
Note that the name Jeriah is spelled יריה in 1 Chronicles 26:31 but with a final ו (waw) in 1 Chronicles 23:19 and 24:23 (Jeriahu). It's quite common that names that ended on יה (yah) also existed ending on יהו (yahu).
🔼Etymology of the name Jeriah
The name Jeriah consists of two elements, the final part being יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton יהוה, YHWH, or Yahweh.
It's not clear where the first part of our name comes from. The scholars behind the NOBSE Study Bible Name List think its origin lies in the verb ראה (ra'a), meaning to see:
Alfred Jones (Dictionary of Old Testament Proper Names) believes the first part of our name comes from the verb ירא (yara'), meaning to fear or revere, and BDB Theological Dictionary lists our name under the verb ירה (yara) meaning to cast or shoot:
For a meaning of the name Jeriah, NOBSE Study Bible Name List reads Yahweh Sees. Jones' Dictionary of Old Testament Proper Names proposes Fear Of The Lord. And BDB Theological Dictionary does not translate our name but does list under ירה and declares it comparable to the name Jeriel, which BDB translates with Founded Of El. Jeriah would thus mean Founded Of Yah.
