This does not mean a specific priest or prophet. It refers to priests and prophets in general. AT: "The priests and the prophets" (See: [[rc://en/ta/man/translate/figs-genericnoun]])
These two phrases mean basically the same thing and emphasize that the priests and the prophets cannot do their job because they are very drunk. AT: "stumble around because they are drunk" (See: [[rc://en/ta/man/translate/figs-parallelism]])
Their drinking so much that they can no longer think properly is spoken of as if the wine swallowed them. This can be stated in active form. AT: "the wine is causing them to be confused" (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-activepassive]])
