And should one say that it was through human understanding that philosophy was discovered by the Greeks, still I find the Scriptures saying that understanding is sent by God. The psalmist, accordingly, considers understanding as the greatest free gift, and beseeches, saying, “I am Thy servant; give me understanding.” And does not David, while asking the abundant experience of knowledge, write, “Teach me gentleness, and discipline, and knowledge: for I have believed in Thy commandments?” He confessed the covenants to be of the highest authority, and that they were given to the more excellent. Accordingly the psalm again says of God, “He hath not done thus to any nation; and He hath not shown His judgments to them.” The expression “He hath not done so” shows that He hath done, but not “thus.” The “thus,” then, is put comparatively, with reference to the pre-eminence, which obtains in our case. The prophet might have said simply, “He hath not done,” without the “thus.”
