Job 8:7 New English Translation

⁷Your beginning^[a] will seem so small,
since your future will flourish.^[b]

Job 8:7 tn The reference to “your beginning” is a reference to Job’s former estate of wealth and peace. The reference to “latter end” is a reference to conditions still in the future. What Job had before will seem so small in comparison to what lies ahead.
Job 8:7 tn The verb has the idea of “to grow”; here it must mean “to flourish; to grow considerably” or the like. The statement is not so much a prophecy; rather Bildad is saying that “if Job had recourse to God, then….” This will be fulfilled, of course, at the end of the book.
