Three Levitical genealogies in Exodus 6:17, Numbers 3:18, and 1 Chronicles 6:17 list Libni as a son of Gershon (Levi's firstborn). But 1 Chronicles 6:29, tracing a completely different Levitical line, has Libni as son of Mahli and grandson of Merari (Levi's third son). Same name, two different fathers, two different Levitical branches.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.
Gershon
The sons of Gershon; Libni, and Shimi, according to their families.Exodus 6:17
And these are the names of the sons of Gershon by their families; Libni, and Shimei. Numbers 3:18
And these be the names of the sons of Gershom; Libni, and Shimei. 1 Chronicles 6:17
What follows is one scholar’s way of reading this disagreement— a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Genuinely disputed among scholars
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
Three Levitical lists agree that Libni was a son of Gershon (also spelled Gershom), Levi's firstborn: Exodus 6:17 ("the sons of Gershon: Libni and Shimi"), Numbers 3:18 ("the sons of Gershon by their families: Libni and Shimei"), and 1 Chronicles 6:17 ("the sons of Gershom: Libni and Shimei"). But 1 Chronicles 6:29, tracing the Merarite line, lists "Mahli, Libni his son, Shimei his son, Uzza his son" — placing Libni in the line of Merari, Levi's third son, as the son of Mahli. The same name thus appears in two different Levitical branches with two different fathers.
The standard harmonization, found in Keil and Delitzsch and in Archer, posits two distinct men named Libni: one a Gershonite clan-head, the other a Merarite descendant. The point is well taken in principle — Hebrew onomastics reused personal names freely, and the biblical record contains numerous homonymous figures (multiple men named Zechariah, Azariah, Jonathan, and so on). A Gershonite Libni and a Merarite Libni would not, on this view, be a contradiction at all but a coincidence of naming.
What weakens the homonym defense is the literary character of the chapter in which both names occur. First Chronicles 6 is a single, systematically organized genealogical treatise: verses 16-19 set out the three Levitical branches — Gershon, Kohath, Merari — and verse 17 assigns Libni and Shimei to Gershon. The reappearance of "Libni... Shimei" in the Merarite list at verse 29 is striking precisely because the same pair of names (Libni and Shimei) that belongs to Gershon in verse 17 surfaces again in Merari's line, suggesting not an independent homonym but a transmission disturbance — a name displaced or assimilated from the Gershonite list into the Merarite one. Gary Knoppers, in the Anchor Bible commentary on 1 Chronicles, treats verse 29 as textually suspect and notes variation in the versional witnesses; the Septuagint tradition does not transmit the Levitical lists uniformly, and the expected Merarite name (commonly reconstructed as something other than Libni) may have been corrupted in the Masoretic line. Ralph Klein's Hermeneia commentary and Sara Japhet's Old Testament Library commentary likewise approach the Chronicler's Levitical genealogies as a textually unstable corpus assembled from heterogeneous sources, where copyists' errors and harmonizing assimilations are common.
This is why the entry is best classed as disputed rather than as a clean contradiction or a clean harmonization. If the homonym explanation is correct, there is no contradiction, only two men sharing a name. If, as the critical commentators incline to think, verse 29 is corrupt, then the contradiction is real but is an artifact of scribal transmission rather than of authorial intent — and would be resolved by emendation. What the homonym defense cannot claim is that the received text presents two evidently distinct individuals: the Chronicler nowhere distinguishes them, gives no patronymic for the Gershonite Libni that would differentiate him, and repeats the very Gershonite name-pair in the Merarite list without comment. The most economical reading of the transmitted Masoretic text is that the same Libni has been placed in two branches, whether by homonym or, more probably, by corruption.
Where the critical reading lands: contradiction in the text as it stands, most plausibly a scribal corruption in 1 Chronicles 6:29; the two-Libni harmonization is possible but the least economical reading.
