Job 13:15 - Coke's Commentary on the Holy Bible

Though he slay me, &c.— It is impossible to understand this of a temporal deliverance; for how should a man hope for this, though he were slain? This passage, according to another reading, is, "Lo, he will kill; I will not hope; nevertheless, I will argue mine own ways, or plead mine own cause before him. He also shall be my salvation, &c." It is plain that Job here despairs of life, and yet hopes for salvation; which, therefore, must necessarily be understood of a future absolution and reward in the day of judgment. Peters.
