Jamieson, Fausset and Brown on Job 15:2

CHAPTER 15

SECOND SERIES.

Job 15:1-35. Second Speech of Eliphaz.

2. a wise man--which Job claims to be.

vain knowledge--Hebrew, "windy knowledge"; literally, "of wind" (Job 8:2). In Ec 1:14, Hebrew, "to catch wind," expresses to strive for what is vain.

east wind--stronger than the previous "wind," for in that region the east wind is the most destructive of winds (Is 27:8). Thus here,--empty violence.

belly--the inward parts, the breast (Pr 18:8).
