2805. Where is the lamb [pecus] for a burnt-offering? That this signifies, Where are they from the human race who are to be sanctified? is evident from the representation of sacrifices, especially of burnt-offerings. That burnt-offerings and sacrifices were representative of internal worship, may be seen above (n. 922, 923); that they were made from the flock and from the herd; that when made from the flock, they consisted of lambs, sheep, she-goats, kids, rams, he-goats, and when from the herd, of oxen, bullocks, or calves; and that these signified various kinds of celestial and spiritual things (n. 922, 1823, 2180); also that by means of them sanctifications were to be effected (n. 2776). It may be seen from this, that by Isaac's inquiry, "Where is the lamb for a burnt-offering?" is signified, Where are they from the human race who are to be sanctified?-which is more plainly manifest from what follows, that is, from the answer of Abraham his father, "God will see for Himself the lamb for a burnt-offering" (verse 8); by which is signified that the Divine Human will provide those who are to be sanctified. This is also evident from the fact that a ram was afterwards seen behind them, held by the horns in a thicket, which was offered for a burnt-offering (verse 13), by which are signified those of the human race who are of the Lord's spiritual church. And the same is evident from what follows in verses 14 to 17.
