In the Old Testament, God’s Spirit represents an active dimension of His character. Israel was learning to embrace monotheism over polytheism; thus, emphasizing the character and activity of the one true God was more important than distinguishing identities within God. In depicting God’s activity, it was natural to speak in terms of “Spirit” because of the term’s various connotations. The Hebrew term רוּחַ (ruach) can mean “wind,” and “breath”; it can also refer to the life principle of persons or animals. Some passages play on multiple senses.
