“Provide neither gold, nor silver, nor brass in your purses,”
King James Version (KJV)
10:9 Provide not - The stress seems to lie on this word: they might use what they had ready; but they might not stay a moment to provide any thing more, neither take any thought about it. Nor indeed were they to take any thing with them, more than was strictly necessary. Lest it should retard them. Because they were to learn hereby to trust to God in all future exigencies.
Mt 10:9 Provide neither gold, etc. Because "the workman is worthy of his meat" (Mt 10:10) and those to whom they preached should supply all their wants. Compare 1Ti 5:18 1Co 9:7-14. This has always been the law of Christ.
