(Hebrew Yach'ath, יִחִת, prob. for יִחֶדֶת union; Sept. Ι᾿έθ, but Ι᾿εέθ in 1 Chronicles 6:43, and Ι᾿γάθ v.r. Ι᾿άθ in 1 Chronicles 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 (1 Chronicles 23:10); yet no such son is mentioned in 1 Chronicles 23:9, where the three sons of Shimei are by some error (probably the transposition of the latter clause) attributed to his brother Laadan, while in 1 Chronicles 23:11 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 (1 Chronicles 6), where Jahath (1 Chronicles 6:43) occurs as the son of Gershom (prob. by the transposition of Shimei's name into the preceding verse), and again (1 Chronicles 6:20) as a son of Libnah (i.e. Laadan), instead of Shimei (comp. Zimnah, the son of Jahath, 1 Chronicles 6:20; 1 Chronicles 6:42). B.C. considerably post 1856.
2. Son of Reaiah (or Haroeh), of the posterity of Hezron, and father of two sons (1 Chronicles 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 (1 Chronicles 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 (2 Chronicles 34:12). B.C. 623.
