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.

923. And he offered burnt-offerings on the altar. That this signifies all worship therefrom, is evident from what has been already said. Burnt-offerings were the principal things of the worship of the representative church, and so thereafter were sacrifices, concerning which, of the Lord’s Divine mercy hereafter. That “burnt-offerings” taken in the complex signify representative worship, is evident also in the Prophets, as in David:

Jehovah will send thee help from the sanctuary, and strengthen thee out of Zion; He will remember all thy offerings, and accept as fat thy burnt-offering (Psalms 20:2-3).

In Isaiah:

Whoso keepeth the sabbath from profaning it, them will I bring in to My holy mountain; their burnt-offerings and their sacrifices shall be accepted upon Mine altar (Isaiah 56:6-7),

where “burnt-offerings and sacrifices” denote all worship; “burnt-offerings” worship from love, “sacrifices” worship from the derivative faith. As is usual in the Prophets,” internal things are here described by external.
