על אברהם מ״גOn Abraham 43

א׳
1[247] Many a story I could relate in praise of this woman, but one I will mention which will be the clearest proof that the others are true. Being childless and barren and fearing lest the house beloved of God should be left entirely desolate,
ב׳
2[248] she came to her husband and said: “Long have we lived together in mutual goodwill. But the purpose for which we ourselves came together and for which nature formed the union of man and wife, the birth of children, has not been fulfilled, nor is there any future hope of it, through me at least who am now past the age.
ג׳
3[249] But do not let the trouble of my barrenness extend to you, or kind feeling to me keep you from becoming what you can become, a father, for I shall have no jealousy of another woman, whom you will take not for unreasoning lust but in fulfillment of nature’s inevitable law.
ד׳
4[250] And therefore I shall not be backward to lead to you a bride who will supply what is lacking in myself. And if our prayers for the birth of children are answered the offspring will be yours in full parenthood, but surely mine also by adoption.
ה׳
5[251] But to avoid any suspicion of jealousy on my part take if you will my handmaiden, outwardly a slave, inwardly of free and noble race, proved and tested by me for many years from the day when she was first brought to my house, an Egyptian by birth, but a Hebrew by her rule of life.
ו׳
6[252] We have much substance and abundance of wealth, not on the usual scale of immigrants, for in this we now outshine those of the native inhabitants who are noted for their prosperity, but no heir or successor has appeared, though there may be if you follow my advice.”
ז׳
7[253] Abraham with increased admiration for the wifely love, which never grew old and was ever showing itself anew, and her careful forethought for the future, took the mate whom she had approved and kept her till she had borne a child, or, as the surest version of the story runs,  only till she became pregnant, and when this occurred not long after he abstained from her through his natural continence and the honour which he paid to his lawful spouse.
ח׳
8[254] So a son was born just at that time to the handmaiden, but long afterwards the wedded pair, who had despaired of the procreation of children, had a son of their own, a reward for their high excellence, a gift from God the bountiful, surpassing all their hopes.
