7781. 'And all the firstborn of the beasts' means adulterated forms of the good of faith. This is clear from the meaning of 'the firstborn' as faith; and from the meaning of 'beast' as affections for good, and in the contrary sense affections for evil, dealt with in 45, 46, 141, 143, 246, 714, 715, 719, 776, 2179, 2180, 3519, 4724, 5198. Such things come to be meant by 'beasts' from representatives in the next life, 3218; and for that reason also such things were meant by the ones used in sacrifices, 2180, 2805, 2807, 2870, 3519. And because 'beasts' meant these things 'the firstborn of the beasts' therefore means the good of truth, at this point when it had been adulterated since it was with the Egyptians, who perverted all truths and forms of good by applying them to evil purposes.

2805. 'Where is the animal for a burnt offering?' means, Where are those members of the human race who are to be sanctified? This is clear from the representation of sacrifices, in particular burnt offerings. Burnt offerings and sacrifices were representative of internal worship, see 922, 923; they were made from the flock and from the herd - when from the flock, lambs, sheep, she-goats, kids, rams, or he-goats were used, when from the herd, oxen, young bulls, or calves, all of which meant various kinds of celestial and spiritual things - see 922, 1823, 2180; and by means of them people were sanctified, 2776. From all this it may become clear that Isaac's question, 'Where is the animal for the burnt offering?' means, Where are those members of the human race who are to be sanctified? The same is more plainly evident from what comes next, that is to say, from the reply made by Abraham his father, 'God will see for Himself to the animal for a burnt offering', verse 8, which means that the Divine Human will provide those who are to be sanctified; from the fact that later on he saw a ram behind him caught by its horns in a thicket, and offered that as the burnt offering, verse 13, which means members of the human race who belong to the Lord's spiritual Church; as well as from the details that follow after this in verses 14-17.
