🔼The name Romamti-ezer in the Bible
There's only one man in the Bible with the elaborate name Romamti-ezer. He was one of the fourteen sons of the famous musician Heman, who worked in the temple during the days of king David (1 Chronicles 25:4, spelled רממתי עזר). Under the direction of their father, these men sang and played various instruments during services of worship of the God of Israel. And when the less noble duties had to be assigned, Romamti-ezer and twelve of his sons and relatives, caught the twenty-fourth lot (1 Chronicles 25:31, spelled רוממתי עזר).
🔼Etymology of the name Romamti-ezer
The name Romamti-ezer obviously consists of two elements. The first part appears to be reminiscent of the noun רוממות (romemut), meaning uplifting, arising, from the verb רום (rum), meaning to be high. Or (as the sources we routinely consult insist) it's a first person form of a grammatical category (namely the Piel stem) that turns a verb (to be high) into a transitive verb (to cause to rise). That would also cause the final מ (mem) of the verb רום to double. But all agree that the first segment of our name comes from the following:
If this first segment is a noun, the letter י (yod) upon which this segment ends may either create a possessive form (my uplifting, or uplifting of), or it may form an adjective (ascending), or it may be a remnant of יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton יהוה, YHWH, or Yahweh.
The second part of our name comes from the verb עזר (azar), meaning to help or support:
All together, if we take the first part of the name Romamti-ezer to be a noun, it would mean something like My Ascent Supports, or Rise Of Enclosure. But that appears to be not the most attractive interpretation. For a meaning of the name Romamti-ezer, NOBSE Study Bible Name List reads I Have Raised Up Help and Jones' Dictionary of Old Testament Proper Names has I Have Lifted Up Help. BDB Theological Dictionary appears to apply the rising part as an adjective and proposes I Have Made Lofty Help.
