Genèse 5:24

And Hanok served in the truth before the Lord; and, behold, he was not with the sojourners of the earth; for he was withdrawn, and he ascended to the firmament by the Word before the Lord, and his name was called Metatron the Great Saphra.

ויתהלך, similar to Genesis 48,15 ויתהלכו אבותי לפניו, “before Whom my forefathers walked.” The wording means that Chanoch channeled all his love and desire into fulfilling the will of G’d, and he acquired a deep understanding of the ways of his Creator already at the age of 65. For the remaining 300 years of his life on earth he walked with G’d. In spite of this, he did not neglect his duties of producing offspring. As a result of his ever more profound study of theological matters he came to despise his body, so that when he no longer performed the commandment of being fruitful and multiplying, G’d decided that he had served his purpose on earth, and He removed him from the earth even though he had lived only less than half a normal lifespan.
ואיננו כי לקח אותו אלוקים, the word ואיננו is meant to convey that he did not die from sickness, nor did he suffer pains before he died. His contemporaries had not considered his impending death as even a remote possibility, so that they were totally unprepared for it. They did not notice his absence until he had actually died. When the Torah employs the unusual phrase כי לקח אותו אלוקים, this is an allusion to the fact that G’d removed his soul to the heavenly regions. We have the same expression in Psalms 73,24 ואחר כבוד תקחני, “You took me toward honour.” Similar uses of the expression occur in Psalms 49,16 כי יקחני סלה, the thrust of the word לקח אלוקים being that instead of death leading to gehinnom, the party described as subject to G’d taking him, is transported by G’d immediately to his life in the hereafter.
On the other hand, the expression cannot be explained in this fashion in Ezekiel 24,16 הנני לוקח את מחמד עיניך במגפה, “see I shall take from you the darling of your eyes, by the plague.” Even though the verse is introduced by the word הנני which always introduces something constructive, positive, and which might mislead the reader into thinking that what follows will be something good, something pleasant, the word במגפה, by the plague, makes it plain that being deprived of his wife is not presented by G’d as a positive experience for the prophet. It implies that not only will the prophet suffer mentally, but his wife will suffer physically. Also in Exodus 21,35 when the expression כי יגוף (same root) is used it is followed by the words ומת, that the party who has been gored will die as a result of such a goring. All this proves that מגפה is descriptive of a painful disease, or injury. On the …
