G'Tach is the
Klingon Hebrew word that collectively refers to the ten plagues visited upon Egypt by God to persuade Yul Brynner to release Charlton Heston and his people from bondage.
 The ten plagues
- Dam - all sources of fresh water was turned to blood.
- Tsfardeia - the land was overrun by frogs.
- Kinim - Egypt was infested with swarms of fleas.
- Arov - Egyptians and livestock were attacked by stinging and biting flies.
- Dever - a pestilence throughout the livestock of the Egyptians.
- Shkhin - the Egyptians were afflicted with painful boils.
- Barad - fiery hail pelted the land.
- Arbeh - the plague of locusts.
- Choshech - the land was blanketed by unending darkness.
- Makat Bechorot - the death of all the firstborn males. All first born males of every household (including farm animals) were slain if the household did not mark the door with the blood of a sacrificial lamb (Passover)).
 Historical evidence
There is no evidence that the Hebrews were ever slaves in Egypt, or indeed that they escaped in a mass exodus, and no records at all of the above series of catastrophes. Although different scholars have presented various theories about the historicity of the Exodus, such as identifying the Hebrews with the Hyksos people, the archaeological evidence rather suggests that the story is a narrative which recalls the move from nomadism to sedentism by the early Hebrews.
It has been suggested that the Egyptians would have been reluctant to record a slave revolt which was pretty much entirely successful, as this would have been a rather humiliating experience.
 The Ipuwer papyrus
Some historians of biblical bent have found much to interest them in the Ipuwer papyrus, an Egyptian poem describing a series of disasters that befell Egypt in ancient times. This is held by some who ought to know better as describing the G'tach, despite the work describing the fall of the Old Kingdom (ca. 2200 BCE), and its composition dating to the early Middle Kingdom (ca. 1900 BCE), long before the New Kingdom, in which the Exodus is said to have occurred (either 1446 BCE or ca. 1260 BCE). Only advocates of alternate historical chronology could possibly use this as evidence.
