Jah

Jah or Yah (Hebrew: יָהּ‎, Yāh) is a short form of the tetragrammaton יהוה (YHWH), the personal name of God: Yahweh, which the ancient Israelites used.

The conventional Christian English pronunciation of Jah is /ˈdʒɑː/, even though the letter J here transliterates the palatal approximant (Hebrew י Yodh).

While pronouncing the tetragrammaton is forbidden for Jews, articulating "Jah"/"Yah" is allowed, but is usually confined to prayer and study.

[5] The name of the national god of the kingdoms of Israel (Samaria) and Judah is written in the Hebrew Bible as יהוה (YHWH), which modern scholars often render as Yahweh.

In the 1885 Revised Version and its annotated study edition, The Modern Reader's Bible, which uses the Revised Version as its base text, also transliterates "JAH" in Psalms 89:8 which reads, "O LORD God of hosts, who is a mighty one, like unto thee, O JAH?

The modern letter "J" settled on its current English pronunciation only around 500 years ago; in Ancient Hebrew, the first consonant of the Tetragrammaton always represents a "Y" sound.

The Spanish language Reina Valera Bible employs "JAH" in 21 instances within the Old Testament according to the Nueva Concordancia Strong Exhaustiva.
