With the merciful you will show yourself merciful; with an upright man you will show yourself upright;
All Commentaries on Psalms 18:25 Go To Psalms 18
Augustine of Hippo
AD 430
26. "With the holy Thou shalt be holy" (ver. 25). There is a hidden depth also, wherein Thou art known to be holy with the holy, for that Thou makest holy. "And with the harmless Thou shalt be harmless." For Thou harmest no man, but each one is bound by the bands of his own sins.
