A Hebrew contraction for JEHOVAH, Ps 68:4. It is often found in Hebrew compound words, as in Adonijah, Malachia, Hallelujah.
Condensing in one emphatic syllable all that is implied in Jahveh (or Yahweh), the true pronunciation of Jehovah (Ps 68:4); first in Ex 15:2 (Hebrew). Often in names, as Eli-jah. Only in poetry: Isa 12:2, "Jah (or Yah) Jehovah is my strength and my song"; (Isa 26:4) "in Jah (or Yah) Jehovah is the Rock of ages." The union of the two names expresses in the highest degree God's unchanging love and power. Hallelu-Jah (or Hallelu-Yah) is "Praise ye Jah (or Yah)". Ps 89:8, "O Jehovah, God of hosts, who, as Thou, is a strong Jah (or Yah)?" the emphatic concentration of the name "Jehovah." The spirit impressed with a sense of God feels the need of repeating frequently that name in which His being is comprehended (Hengstenberg).
An abbreviated form of Jehovah. Ps 68:4. The same Hebrew word occurs many times, and is translated LORD. See GOD.
(Jehovah), the abbreviated form of Jehovah, used only in poetry. It occurs frequently in the Hebrew, but with a single exception,
is rendered "Lord" in the Authorized Version. The identity of Jah and Jehovah is strongly marked in two passages of Isaiah--
JAH, one of the names of God, which we meet with in the composition of many Hebrew words; as, Adonijah, Allelujah, Malachia; that is, "My Lord," "Praise the Lord," "The Lord is my King."
