Ja'hath (Hebrew Yach'ath, יִחִת, prob. for יִחֶדֶת union; Sept. Ι᾿έθ, but Ι᾿εέθ in 1Ch 6:43, and Ι᾿γάθ v.r. Ι᾿άθ in 1Ch 24:22), the name of a descendant of Judah and of several Levites.
1. A son of Shimei and grandson of Gershom, the son of Levi (1Ch 23:10); yet no such son is mentioned in ver. 9, where the three sons of Shimei are by some error (probably the transposition of the latter clause) attributed to his brother Laadan, while in verse 11 Jahath is stated to have been "chief" (i.e. most numerous in posterity) of the four sons of Shimei. A similar disagreement appears in the. parallel passage (I Chronicles 6), where Jahath (ver. 43) occurs as the son of Gershom (prob.
by the transposition of Shimei's name into the preceding verse), and again (ver. 20) as a son of Libnah (i.e. Laadan), instead of Shimei (comp. Zimnah, the son of Jahath, ver. 20, 42). B.C. considerably post 1856.
2. Son of Reaiah (or Haroeh), of the posterity of Hezron, and father of two sons (1Ch 4:2). B.C. post 1612.
3. One of the sons of Shelomoth (or Shelomith). a descendant of Izhar, of the family of Kohath, appointed to a prominent place in the sacred services by David (1Ch 24:22). B.C. 1014.
4. One of the Levitical overseers of the Temple repairs instituted by Josiah; he belonged to the family of Merari (2Ch 34:12). B.C. 623.
