The Spirit in Ezekiel is an intriguing topic that stirs up many recent types of research through books and articles. Because of its richness of Hebrew vocabulary, the word רוּחַ employs different expressions. Ezekiel was known as the `prophet of the spirit” because of his usage of the word רוּחַ, with different meanings, and frequently making the switch within the same context.` Ezekiel not only used the word רוּחַ fifty-two times but also implied the occurrence of each word with its own relevant meaning to the immediate context.` In order to emphasize the function of the spirit, Ezekiel had to use certain features which traditionally came from the prophetic tradition, yet some of them obviously came from his own. Ezekiel 42:15-20 is one of the cases. This study is to discuss the intentional use of רוּחַ by Ezekiel in 42:15-20 both in its context and the context of the whole book.
