20. was ready--not in the Hebrew; "Jehovah was for my salvation," that is, saved me (compare Isa 12:2).
      we--I and my people.
      in the house of the Lord--This song was designed, as many of the other Psalms, as a form to be used in public worship at stated times, perhaps on every anniversary of his recovery; hence "all the days of our life."
      lump of figs--a round cake of figs pressed into a mass (1Sa 25:18). God works by means; the meanest of which He can make effectual.
      boil--inflamed ulcer, produced by the plague.
