Real Bible Translation

And a rhomphaia⁸ will pass through the Soul Life of herself, also of yourself, in such a manner as inner debates should be uncovered from out of hearts multitudinous.

Julia Smith Literal 1876 Translation:
(And also a spear shall pass through the soul of thyself,) so that the reasonings from many hearts might be revealed.

LITV Translation:
yea, a sword also will pierce your own soul, so that the thoughts of many hearts may be revealed.

ESV Translation:
(and a sword will pierce through your own soul also), so that thoughts from many hearts may be revealed.”

Footnotes

The ῥομφαία rhomphaia was originally a "spear" and later a long, curved "sword."

Historical accounts and linguistic sources show that it originally functioned as polearm. Rich’s Dictionary of Antiquities describes it as having a wooden shaft of the same dimensions as the iron head, similar to the Roman pilum (javelin).

Hesychius lists ῥομφαία as μάχαιρα, ξίφος, ἤ ἀκόντιον μακρόν, indicating it could be a sword, long blade, or even a javelin-like weapon. Additionally, the Dacian falx, a similar weapon, had long-handled variants used with two hands, further supporting the idea that some ῥομφαίαι were polearm-like.

Roman military adaptations against Thracian and Dacian warriors—such as reinforcing helmets—suggest that these weapons had enough length and impact force to be effective in breaking shields and armor, a characteristic of polearms and long two-handed weapons.
