Here is Charles Spurgeon's commentary on Psalm 37:34-
"Wait on the Lord." We have here the eighth precept, and it is a lofty eminence to attain to. Tarry the Lord's leisure. Wait in obedience as a servant, in hope as an heir, in expectation as a believer. This little word "wait" is easy to say, but hard to carry out, yet faith must do it. "And keep his way." Continue in the narrow path; let no haste for riches or ease cause unholy action. Let your motto be, "On, on, on," Never flag, or dream of turning aside. "He that endureth to the end, the same shall be saved." "And he shall exalt thee to inherit the land." Thou shalt have all of earthly good which is really good, and of heavenly good there shall be no stint. Exaltation shall be the lot of the excellent. "When the wicked are cut off, thou shalt see it." A sight how terrible and how instructive! What a rebuke for fretfulness! what an incentive to gratitude! My soul, be still, as thou foreseest the end, the awful end of the Lord's enemies.
