Ezekiel 36:27

put my spirit This great promise is one which does not appear prominently in the prophets till the exile. In Isaiah 11 the Messianic king has the spirit of Jehovah in all the manifoldness of his operation, and in Ezekiel 32:15 the hope is expressed that "the spirit shall be poured on us from on high" (though the passage is held by some to be later than Is.); but it is in exile and post-exile times that the idea is first expressed with great certainty, e.g. Ezekiel 36:27; Ezekiel 37:14; Joel 2:28; Zechariah 4:6 (Ezekiel 12:10). Jeremiah does not use the expression, though his promise that Jehovah will write his law on men's hearts seems to have much the same sense, or at least it expresses the "new spirit" of Ezek., and in the New Testament this new spirit is the spirit of God. There always attaches to "spirit" the idea of power in operation, the spirit of God is God exerting power.

to walk in my statutes Being endowed with the spirit of God they will walk in his statutes, for these are expressions of his spirit. The spirit of God will appear both as an inward impulse to fulfil God's will, and as a power to do it. In the Old Testament the spirit of God, even the prophetic spirit, is usually a dynamic influence, an elevation of the natural human faculties. The "statutes and judgments" are not the mere external enactments of the law; they embrace all the moral laws to which Ezek. so often refers (e.g. ch. 18, 22, 33), and it is doubtful if the prophet refers specially to written laws at all.
