Matthew Poole and continuators on Job 11:15

15 For then shalt thou lift up thy face without spot , yea, thou shalt be stedfast , and shalt not fear.

Which notes chearfulness, and holy boldness and confidence; as a dejected Countenance notes grief and shame. See Gen. 4. 5, 6. 2 Sam. 2. 22. Iob 22. 26. Luke 21. 28.

Or, Being without spot: So it is only an Ellipsis of the Verb Substantive, which is most frequent. And this fitly follows as the ground of his confidence, because he should in this case have a clear and unspotted Conscience, and a sense of his own innocency. Or without blemish, as the word properly signifies; i. e. without any sense of guilt, or any shame consequent upon it either from God or men. The ground of the expression is this, That when mens faces are spotted with dirt, they are ashamed to shew them. And Iob was charged by his friends, as having many spots upon him, yea, such as were not the spots of God's Children.

Or, firm or fixed: Either 1. as to his outward Condition, which should be constantly prosperous. Or rather as to his Mind, which should have strong and comfortable assurance of God's favour, and of his own safety and happiness: For this stedfastness is opposed unto that fear, which is incident to wicked men; who, even when they are free from actual miseries, yet oft-times are tormented with the dread of them.
