Ezekiel 37:9

‘Then he said to me, “Prophesy to the spirit (wind, breath), prophesy, son of man, and say to the spirit (wind), Thus says the Lord Yahweh, Come from the four winds, O spirit, and breathe on these dead men that they may live.” '

But then he was to call on the spirit/breath/wind calling it to breathe on the dead that they might live. There is a strong play on the different meanings of ruach, which can mean spirit, breath or wind. The winds are seen as providing lifegiving breath so that the corpses might live, but we must remember that Yahweh comes on the wings of the wind (Eze 1:4; 2 Samuel 22:11; Psalms 18:10; Psalms 104:3). And the wind is elsewhere closely connected with the activity of the Spirit of God (2 Samuel 5:24; Acts 2:2), and thus it is clear that what happens here is the result of the work of God's Spirit. It is like a new creation (Psalms 33:6).

So Ezekiel learned the important lesson that we must all learn, that His work manward must be paralleled by his looking Godward, and that without the latter the former will be useless.
