243. And white garments, that thou mayest be clothed. That this signifies genuine truths and intelligence therefrom, is evident from the signification of white garments, as being genuine truths; for garments signify truths (as may be seen above, n. 195), and white signifies what is genuine, and is said of truths (as may be seen also above, n. 196); and from the signification of to clothe as being to procure for oneself intelligence therefrom, for by means of genuine truths all intelligence is obtained; for the human understanding is formed to receive truths, therefore such as are the truths of which it is formed, such is its quality. It is believed that it is a matter of the understanding to be able to reason from thought and to speak from falsities, and to confirm them by many arguments; but this is not understanding, it is only a faculty given to man with the memory to which it is adjoined, and of which it is an activity. Nevertheless, the understanding is thereby born and formed, in proportion as man receives truths from affection; but to receive genuine truths from affection is not possible for any man, except from the Lord alone, because they are from Him. Consequently, to receive understanding, or to become intelligent, is imparted to man by the Lord alone, and to every one who applies himself to receive, according to what was said above (n. 239). This therefore is what is signified by, I counsel thee to buy of me white garments, that thou mayest be clothed.

8767. 'And keep My covenant' means thus leading a good life, and as a consequence being joined [to the Lord]. This is clear from the meaning of 'keeping the covenant' as leading a life in accordance with the commandments, thus a life governed by good, and so being joined to the Lord. The reason why 'keeping the covenant' means leading a life in accordance with the commandments, thus leading a good life, is that the stipulations of the covenant were all the things that had been commanded, which were called testimonies, judgements, laws, and statutes, in particular the Ten Commandments. All these were also called the covenant because it was established through them. The fact that keeping them is leading a life in accordance with them is evident from the meaning of 'keeping' in the Word. Many times it speaks of hearing the commandments and keeping them, and in those places 'hearing' means accepting them in faith, and 'keeping' accepting them in life, that is, leading a life in accordance with them. The reason why 'keeping the covenant' also means being joined [to the Lord] is that in an overall sense 'a covenant' means being joined together, 665, 666, 1023, 1038, 1864, 1996, 2003, 2021, 6804. It has this further meaning because a person who leads a life in accordance with the commandments is joined to the Lord. For the commandments teach about life and also impart life, thereby opening the way to heaven and opening one's eyes to see the Lord.
