🔼The name Ishmerai in the Bible
The name Ishmerai occurs only once in the Bible. He is mentioned as one of the sons of Elpaal, son of Shaharaim of Benjamin and his wife Hushim (1 Chronicles 8:18). And that's all we know about this man.
🔼Etymology of the name Ishmerai
The name Ishmerai consists of two elements. The first part is an active form of the verb שמר (shamar I), meaning to keep, guard, observe or give heed:
The letter י (yod) upon which our name ends, may either create an adjective (guard-like), a possessive form (my guard), or may be a remnant of יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton יהוה, YHWH, or Yahweh.
Both NOBSE Study Bible Name List and Jones' Dictionary of Old Testament Proper Names deem the final yod of our name to be a remnant of YHWH. For a meaning of the name Ishmerai, NOBSE reads Yahweh Keeps, and Jones has He Will Be Kept Of The Lord. BDB Theological Dictionary doesn't offer an interpretation of our name but does list it under the verb שמר (shamar I).
