6789. And where is he? Why is this that ye have left the man? That this signifies how without that truth could they be conjoined with the good of the church, is evident from the signification of an "Egyptian," who is here "the man whom they had left," as being true memory-knowledge (see n. 6784); and from the signification of "why is this that ye have left the man?" as being how without that truth could they be conjoined with good, for "to leave the man" here denotes not to be able to be conjoined.
 How the case herein is, shall be told. True memory-knowledge, which is here represented by Moses, is the truth of the external church; this truth arises from the truth which is of the law from the Divine, which truth also is "Moses" (n. 6771, 6780), and the truth which is of the law from the Divine is the truth of the internal church. Unless external truth is from internal truth, it cannot be conjoined with good. Take the Word as an illustration. Unless the internal of the Word flows in with those who read the Word and abide in the literal sense, no conjunction is effected of truth from the Word with good; and the internal of the Word flows in and is conjoined with good when the man esteems the Word holy; and he esteems it holy when he is in good.
 Take as another illustration the Holy Supper. Scarcely any know that the "bread" therein signifies the Lord's love toward the universal human race, and the reciprocity of man; and that the "wine" signifies charity. Nevertheless, with those who receive the bread and wine holily, conjunction is effected with heaven and with the Lord through these; and the goods of love and charity flow in through the angels, who then do not think of bread and wine, but of love and charity (n. 3464, 3735, 5915). Hence it is evident that external truth is conjoined with internal truth when the man is in good, without his knowing it.
