Spirit.
Archimandrite Nikifor’s Biblical Encyclopedia
In general, the word “spirit” is used in Holy Scripture in various senses: for example, in the sense of wind, a movement of air, whether gentle or violent (Gen. 8:1; Eccl. 11:5; John 3:8); sometimes in the sense of the breath of life, as the principle of the lower, animal life (Gen. 6:17; 7:15, and elsewhere; Eccl. 3:21). Sometimes this word denotes bodiless spirits, endowed with mind, will, and power (Acts 23:8; Eph. 2:2; Heb. 1:14); sometimes human souls (Gen. 2:7; Eccl. 12:7; Rom. 8:10, and elsewhere); sometimes the being of God, the divine nature of God, with all its essential attributes (John 4:24); and sometimes, finally, various gifts, ministries, and workings of the Spirit of God (Gen. 41:38; Num. 11:25; 2 Pet. 1:21, and elsewhere), and especially the gracious gifts that accomplish new life in man and serve his sanctification and salvation (John 3:5–8; Acts 2:38; Rom. 8:2; 1 Cor. 2:12–14; 1 Tim. 3:4–7, and elsewhere).
