Psalms 56:7

7. Now this ratio of the single to the double arises, no doubt, from the ternary number, since one added to two makes three; but the whole which these make reaches to the senary, for one and two and three make six. And this number is on that account called perfect, because it is completed in its own parts: for it has these three, sixth, third, and half; nor is there any other part found in it, which we can call an aliquot part. The sixth part of it, then, is one; the third part, two; the half, three. But one and two and three complete the same six. And Holy Scripture commends to us the perfection of this number, especially in this, that God finished His works in six days, and on the sixth day man was made in the image of God. And the Son of God came and was made the Son of man, that He might re-create us after the image of God, in the sixth age of the human race. …

15. “A clean heart create in me, O God” ( ver. 10 ). “Create”, he meant to say, “as it were begin something new.” But, because repentant he was praying (that had committed some sin, which before he had committed, he was more innocent), after what manner he hath said “create” he showeth. “And a right spirit renew in my inner parts.” By my doing, he saith, the uprightness of my spirit hath been made old and bowed. For he saith in another Psalm, “They have bowed my soul.” And when a man doth make himself stoop unto earthly lusts, he is “bowed” in a manner, but when he is made erect for things above, upright is his heart made, in order that God may be good to him. For, “How good is the God of Israel to the upright of heart!” Moreover, brethren, listen. Sometimes God in this world chastiseth for his sin him that He pardoneth in the world to come. …

11. And what have they done to Thee, O Lord? Let the Prophet here exult! For above, all those verses the Lord was speaking: a Prophet indeed, but in the person of the Lord, because in the Prophet is the Lord.…“Be exalted,” he saith, “above the Heavens, O God.” Man on the Cross, and above the Heavens, God. Let them continue on the earth raging, Thou in Heaven be judging. Where are they that were raging? where are their teeth, the arms and arrows? Have not “the stripes of them been made the arrows of infants”? For in another place a Psalm this saith, desiring to prove them vainly to have raged, and vainly unto frenzies to have been driven headlong: for nothing they were able to do to Christ when for the time crucified, and afterwards when He was rising again, and in Heaven was sitting. …

O. Lo! what the prophet said is fulfilled:“They have digged a pit before me, they have fallen into the midst thereof themselves.”
