4 “Let them be confounded who do vain things unrighteously.” Let them be confounded who act unrighteously for the acquiring things that pass away. “Make Your ways, O Lord, known to me, and teach me Your paths”: not those which are broad, and lead the many to destruction; but Your paths, narrow, and known to few, teach Thou me.
