Job 11:13 - Exposition

If thou prepare thine heart . Having indicated God's righteousness by these general remarks ( Job 11:7-12 ), and implied that Job's complaints are vain and futile, Zophar, in conclusion, addresses Job once more directly: "If thou ( אתּה ) prepare thine heart," cleanse it, that is, of all defilement, direct it, and set it straight (see Psalms 78:8 ) before God, then such and such results (set forth in verses 15-19) will follow. And stretch out thine hands toward him. The outward act of worship must follow the inward movement of the heart, for the turning to God to be complete.
