Concerning Isaac The Legitimate Son Of Abraham.  
1. Now Abraham greatly loved Isaac, as being his only begotten 27 and given to him at the borders of old age, by the favor of God. The child also endeared himself to his parents still more, by the exercise of every virtue, and adhering to his duty to his parents, and being zealous in the worship of God. Abraham also placed his own happiness in this prospect, that, when he should die, he should leave this his son in a safe and secure condition; which accordingly he obtained by the will of God: who being desirous to make an experiment of Abraham's religious disposition towards himself, appeared to him, and enumerated all the blessings he had bestowed on him; how he had made him superior to his enemies; and that his son Isaac, who was the principal part of his present happiness, was derived from him; and he said that he required this son of his as a sacrifice and holy oblation. Accordingly he commanded him to carry him to the mountain Moriah, and to build an altar, and offer him for a burnt-offering upon it for that this would best manifest his religious disposition towards him, if he preferred what was pleasing to God, before the preservation of his own son.

It was that mountain upon which king David afterwards built the temple. 28 Now they had brought with them every thing necessary for a sacrifice, excepting the animal that was to be offered only. Now Isaac was twenty-five years old. And as he was building the altar, he asked his father what he was about to offer, since there was no animal there for an oblation:—to which it was answered, "That God would provide himself an oblation, he being able to make a plentiful provision for men out of what they have not, and to deprive others of what they already have, when they put too much trust therein; that therefore, if God pleased to be present and propitious at this sacrifice, he would provide himself an oblation."
 
3. As soon as the altar was prepared, and Abraham had laid on the wood, and all things were entirely ready, he said to his son, "O son, I poured out a vast number of prayers that I might have thee for my son; when thou wast come into the world, there was nothing that could contribute to thy support for which............
