Having Jesus In Your Heart 24

“Whenever you enter a city or village, search for a worthy person and stay in his home until you leave town. When you enter the home, give it your blessing. If it turns out to be a worthy home, let your blessing stand; if it is not, take back the blessing. If any household or town refuses to welcome you or listen to your message, shake its dust from your feet as you leave. I tell you the truth, the wicked cities of Sodom and Gomorrah will be better off than such a town on the judgment day. Matthew 10:11-15 (NLT)

By 'peace' are signified all things in a complex whole that are from the Lord, and consequently all the things of heaven and the Church; also the blessedness of life in them. These are of peace in the supreme or inmost sense. It follows, therefore, that charity, spiritual security and internal rest are 'peace', for when a man is in the Lord he is in the peace with the neighbour that is charity, in the protection against the hells that is spiritual security; and when he is in peace with the neighbour and in protection against the hells, he is in internal rest from evils and untruths. Apocalypse Revealed n.306

It was from this signification that the Lord commanded His disciples to shake off the dust of their feet if they were not received, as in Matthew:

Whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet. Verily I say to you, it shall be more tolerable for the land of Sodom and Gomorrah in the day of judgment, than for that city (Matt. 10:14-15; Mark 6:11; Luke 9:5; 10:10-12);

by the "disciples" here are not meant disciples, but all things of the church, thus all things of faith and charity (n. 2089, 2129, 2130, 3354, 3858, 3913, 6397); by "not receiving, and not hearing," is signified to reject the truths of faith and the goods of charity; and by "shaking off the dust of the feet," damnation. That "it would be more tolerable for Sodom and Gomorrah than for that city," is because by "Sodom and Gomorrah" are meant those who are in evil of life, but who have known nothing of the Lord and the Word, and thus could not receive. From this it can be seen that there is not meant a house or city which would not receive the disciples, but those who are within the church and do not live the life of faith. Everyone can see that a whole city could not be damned because they did not receive the disciples and at once acknowledge the new doctrine which they preached. Secrets of Heaven  n.7418

As "dust" signifies those who do not regard spiritual and celestial things, but only what is corporeal and earthly, therefore the Lord enjoined His disciples that if the city or house into which they entered was not worthy, they should "shake off the dust of their feet" (Matt. 10:14). (That "dust" signifies what is condemned and infernal, will be further shown at verse 19.) Secrets of Heaven n.24

Whosoever shall not receive you, nor hear your words, as ye go out of that house or that city, shake off the dust of your feet (Matt. 10:14; Mark 6:11; Luke 9:5);

where the "dust of the feet" has a signification like that of a "shoe," namely, uncleanness from evil and falsity, because the sole of the foot is the ultimate natural. They were commanded to do this because they were at that time in representatives, and thought that heavenly arcana were stored up in these alone, and not in naked truths. Secrets of Heaven n.1748

It was the custom for travelers, when they came into any house, to wash their feet; as when the brethren of Joseph were introduced into Joseph's house (Gen. 43:24); and when the Levite and his attendant were received into the house of the old man (Judges 19:21); and when Uriah on his return home was commanded by David to go down to his house and to wash his feet (2 Sam. 11:8). The reason was that traveling and journeying signified what relates to instruction, and thence to life (see n. 1293, 1457, 1463, 2025); and that these were to be purified was shown above; and further, lest the impurity understood in the spiritual sense should adhere, and defile the house, that is, the man; as is also evident from the fact that the disciples were to shake off the dust of the feet, if the city or the house would not receive peace (Matt. 10:14). Secrets of Heaven n.3148

That "dust" signifies what is condemned, is because the earth over the hells in the spiritual world consists of mere dust without grass and herbage. Apocalypse Revealed n.788
