Charles H. Spurgeon on Psalms 43:1

Ungodly...deceitful...unjust. There are ungodly men who, being destitute of religious principle, will not scruple to injure us, when they can thereby gratify their passions or advance their worldly interests. There are deceitful men who will put on the garb of friendship, and acquire our confidence and esteem, and then treacherously cheat us out of our property, or our reputation, or our peace. There are unjust men, who by fraud or by violence, would rob us of our dearest rights and most valuable possessions, and not only reduce our powers and opportunities of doing good, but even diminish our means of comfortable subsistence. And there are oppressors, who taking advantage of our weakness or dependence, and trampling alike on the maxims of equity and humanity, may exact from us unreasonable services, impose upon us heavy burdens and cruel restraints, and ply us with insults, and harassments, and deprivations, from which we can make no escape, and for which we can find no redress. Andrew Thomson, D.D., in "Lectures on Portions of the Psalms." 1826.
