Alternate translation: [The firstborn of death devours parts of his skin; it devours his parts]

Note 2 topic: figures-of-speech / idiom

בְּכ֣וֹר מָֽוֶת

(Some words not found in UHB: consumes parts_of his_skin_of,his consumes parts_of,his firstborn_of death )

The expression the firstborn of death means the strongest kind of death or a terrible kind of death. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [a deadly disease]

Note 3 topic: figures-of-speech / possession

בַּ֝דָּ֗י⁠ו

(Some words not found in UHB: consumes parts_of his_skin_of,his consumes parts_of,his firstborn_of death )

Since the pronoun his in this possessive form refers to the wicked person as a whole, it is likely that the word parts describes his arms and his legs. Alternate translation: [his arms and his legs]
