2496. THE CONTENTS. In the twelfth chapter above, Abraham's sojourning in Egypt has been treated of; by which was signified the Lord's instruction in memory-knowledges while still a boy. In this chapter the subject treated of is Abraham's sojourn in Gerar, where Abimelech was; by which the Lord's instruction is in like manner signified, but in the doctrinal things of charity and faith. The subject that is especially treated of here is the doctrine of charity and faith in respect to its origin; namely, that it is spiritual from a celestial origin, but is not from the rational.
