Cyril of Jerusalem, on Zech 12:1

“The burden of the word of the Lord upon Israel. Thus saith the Lord, who stretcheth forth the heavens, and layeth the foundations of the earth, and formeth the spirit of man in him:”

“There are many statements of spirit in general in the sacred Scriptures, and a person could easily become confused from ignorance, if he did not know to what sort of spirit the particular text refers; therefore we must be sure of the nature of the Holy Spirit according to Scripture. For example, Aaron is called Christ (anointed), and David also, and Saul and others are called christs, yet there is only one true Christ; similarly, since the name of spirit has been given to many things, we must determine what in particular is called the Holy Spirit. Many things are called spirits; our soul is called spirit; this wind, which is blowing, is called spirit; great valor is called spirit; impure action is called spirit; and a hostile devil is called spirit. Take care, therefore, when you hear such things, not to mistake one for another because of the similarity of the name. Scripture says of the soul, "When his spirit departs, he returns to the earth"; and again of the soul: "Who forms the spirit of man within him."”
