Понятие силы nht возникает у египтян. Это понятие встречается в (позднем) рассказе о фараоне Хаэмуасе (сыне Мернептеха XIX династии, которого известная стела) и Нанеферкаптахе, где оно означает нечто вроде божественного ангела.. Вот этот отрывок:
I enchanted the heaven, the earth, the underworld, the mountains, the seas; I discovered the things that the birds of the heaven, the fishes of the sea and the animals say, all. I read another 2. formula of writing ; I saw the Sun rising in heaven, with his cycle of gods; I saw the Moon rising with all the stars in heaven with their nature ; I saw the 3. fishes in the deep, there being power of god resting in water over them. I not doing writing,-I mean (in comparison) to Ne-nefer-lta-Ptah my elder brother, who was a good scribe and learned man exceedingly-he caused to be brought a piece 4. of new papyrus unto him. He wrote every word that was on the roll (before him), all. He caused it to be soaked with beer (?), he melted it in (?) water, he ascertained that it was melted, he drank it, he knew according to that in which it was contained (?). 5. We returned to Coptos on the day named. We made a good day before Isis of Coptos and Harpo- chrates. We embarked on board, we travelled down, we reached the north of Coptos by one schoenus. Behold Thoth had (?) learned everything that had become of 6. (of) Ne-nefer-ka-Ptah about the book. Thoth did not delay. He pleaded before the Sun saying, ' Know my right and my judgement (?) with Ne-nefer-ka-Ptah the son of Pharaoh Mer-neb(?)-Ptah (?). He went to my chamber 7. he plundered it, he took my box with my document (?). He slew my custodian that was guarding it.' They said to him, ' He is before thee with every person belonging to him, all.' A Power of God was sent down 8. from heaven, saying, ' Do not allow Ne-nefer-ka- Ptah to go to Memphis, he prospering with every person belonging to him, all: At a moment, that which happened, Mer-ab the child came out from under the shade of the pleasure-boat g. of Pharaoh. He fell into the river, he did the will of Ra. Every person that was on board uttered a cry, all. Ne-nefer-ka-Ptah came out from under his tent, he spake a writing to him, he made him leap up, there being 10. power of god as (?) water resting upon (?) him
Сам иероглиф НХТ с изображением ножа в руке, вроде бы, гораздо более древний и встречается уже на картуше фараона Джосера III династии.
hieroglyph for Nht: the ‘Strong Arm’
Ступенчатая пирамида Джосера в Саккаре.
С Библейским словом כח тоже все непонятно.
