Sorry to hurt your feelings but that is malarkey. And malarkey is not a Hebrew word and probably isn’t Irish either. And BTW, what sort of word is "troup"?
The second major source of loanwords to Old English were the Scandinavian words introduced during the Viking invasions of the 9th and 10th centuries. In addition to a great many place names, these consist mainly of items of basic vocabulary, and words concerned with particular administrative aspects of the Danelaw (that is, the area of land under Viking control, which included extensive holdings all along the eastern coast of England and Scotland).
The Vikings spoke Old Norse, a language related to Old English in that both derived from the same ancestral Proto-Germanic language. It is very common for the intermixing of speakers of different dialects, such as those that occur during times of political unrest, to result in a mixed language, and one theory holds that exactly such a mixture of Old Norse and Old English helped accelerate the decline of case endings in Old English.[2]
Apparent confirmation of this is the fact that simplification of the case endings occurred earliest in the north and latest in the southwest, the area farthest away from Viking influence. Regardless of the truth of this theory, the influence of Old Norse on the lexicon of the English language has been profound: responsible for such basic vocabulary items as sky, leg, the pronoun they, the verb form are, and hundreds of other words.[3]

There is simply no proof, no credible evidence that ancient Hebrews (Jeremiah and his "troup") travelled to England and Ireland 2,500 years ago and even “if” there were any Hebrews who did, they left no influence on the language or on the culture. The Vikings on the other hand had a profound influence.
About 1/3 of English vocabulary is Hebrew derived words.
