Psalms 7:14 - Ellicott's Commentary On The Whole Bible

Behold, he travaileth. — The poet’s thought recurs to the calumniator, whose sin has deserved all this Divine wrath, and he sees the truth that God’s judgments are not arbitrary, but follow naturally on sin as its consequence. The verb “travaileth” gives the general figure, which is elaborated in the two clauses which describe the stages of conception and pregnancy. (For the image, comp. Job 15:35.)
