LXXVII. (217) On the other hand, you will find virtue not only conceiving with extraordinary joy, but also bringing forth her good offspring with laughter and cheerfulness; and you will also find the offspring of the two parents to be actually cheerfulness itself. Now that the wise man becomes a parent with joy, and not with sorrow, the word of God itself will testify to us when it speaks thus: “And God said unto Abraham, Sarai, thy wife, shall no longer be called Sarai, but her name shall be Sarah; I will bless her, and give thee a son from Her.”{110}{#ge 17:15. Sarah is interpreted Princess in the margin of the Bible.} And, afterwards, Moses proceeds to say, “And Abraham fell upon his face and laughed, and said, æShall a son be born to him who is a hundred years old; and shall Sarah, who is ninety years old, have a son?’ “( 218) Abraham, therefore, appears here to be in a state of joy, and to be laughing because he is about to become the father of happiness, that is to say, of Isaac; and virtue, that is to say, Sarah, laughs also. And the same prophet will further bear witness, speaking thus, “And it had ceased to be with Sarah after the manner of women, and she laughed in her mind and said, such happiness has never yet happened to me to this time, and my lord,” that is to say, the divine Lord, “is older than I;” in whose power, however, this thing must inevitably be, and in whose power it is becoming to place confidence. For the offspring is laughter and joy. For this is the meaning and interpretation of the name of Isaac. Therefore, let the outward sense be grieved, but let virtue be always rejoicing. (219) For, also, when happiness, that is Isaac, was born, she says, in the pious exaltation, “The Lord has caused me laughter, and whoever shall hear of it shall rejoice with Me.”{111}{#ge 21:7.} Open your ears, therefore, O ye initiated, and receive the most sacred mysteries. Laughter is joy; and the expression, “has caused,” is equivalent to “has begotten.” So that what is here said has some such meaning as this, “The Lord has begotten Isaac.” For he is the father of perfect nature, sowing and begetting happiness in the soul.
