1 tn The Hebrew is דַעַת־רוּחַ (da’at-ruakh). This means knowledge without any content, vain knowledge.
2 tn The image is rather graphic. It is saying that he puffs himself up with the wind and then brings out of his mouth blasts of this wind.
3 tn The word for “east wind,” קָדִים (qadim), is parallel to “spirit/wind” also in Hos 12:2. The east wind is maleficent, but here in the parallelism it is so much hot air.
