C. F. Keil and Franz Delitzsch on 1 Chronicles 2:25

1Ch 2:25

Four sons were born to Jerahmeel by his first wife. Five names indeed follow; but as the last, אחיּה, although met with elsewhere as a man’s name, is not ranged with the others by ו copul., as those that precede are with each other, it appears to be the name of a woman, and probably a מ has fallen out after the immediately preceding ם. So Cler., J. H. Mich., Berth. This conjecture gains in probability from the mention in 1Ch 2:26 of another wife, whence we might expect that in 1Ch 2:25 the first wife would be named.
