Psalms 138:7,8 - Joseph Benson’s Commentary on the Old and New Testaments

Though I walk in the midst of trouble That is, be compassed with dangers; thou wilt revive me Thou wilt cheer my spirit and preserve my life. Thou shalt stretch forth thy hand Put forth thy almighty power; against the wrath of mine enemies To oppose and restrain their rage. The Lord will perfect that which concerneth me Will finish that great work of my deliverance and advancement, which he hath undertaken, and carried on hitherto. Thy mercy endureth for ever It is not inconstant and changeable, as men's affections are, but everlasting. And this may be either produced as a proof of the foregoing assertion, The Lord will perfect, &c. Or, as an argument to enforce the following petition. Forsake not Do not withdraw thy presence from me, who am thy creature, but continue to support and save me. Or, leave not, or, do not desist from, or, cease to carry on, as תר Š, rather signifies, the work, namely of my salvation, which is thus far advanced, not by any human help, but by thy power and providence.
