🔼The name Sheariah in the Bible
The name Sheariah occurs twice in the Bible but in the exact same context. Sheariah is one of the six sons of Azel of Benjamin according to 1 Chronicles 8:38 and 9:44. No further details about this man are known.
🔼Etymology of the name Sheariah
The name Sheariah consists of two elements, the final one being יה (Yah), which is an abbreviated form of the Tetragrammaton יהוה, YHWH, or Yahweh.
The first part of the name Sheariah (which the Masoretes decided to endow with a שׁ, shin with the dot to the right) comes from any of the roots שער:
Both NOBSE Study Bible Name List and Jones' Dictionary of Old Testament Proper Names derive Sheariah from root שׁער (sha'ar II), meaning to calculate or reckon. Hence, for a meaning of the name Sheariah, NOBSE reads Yahweh Has Esteemed and Jones has the rather curious Estimated Of The Lord.
BDB Theological Dictionary on the other hand doesn't offer an interpretation of the name Sheariah but lists it under שׁער (sh'r I). Following BDB's hint would lead to a meaning of Gate Of Yah.
