Matthew 10:9

“Provide neither gold, nor silver, nor brass, etc.] That is, not any sort of “money”, as both Mark and Luke express it: for money was then coined, as now, of these three sorts of metals, and which include all kind of money; so that they were not to provide, get, prepare, or take along with them for their journey, as not gold, nor silver, or any parcel of this sort of money, which might be of considerable importance, and lasting consequence to them; so neither brass money, as, halfpence, and farthings, the least, and most inconsiderable: they were forbidden to carry any of either sort in your purses: or, as it may be rendered, “in”, or “within your girdles”; in which travellers, among the…”

“Provide neither gold, nor silver, nor brass in your purses--"for" your purses; literally, "your belts," in which they kept their money.”

“See also Mark 6:8-11, and Luke 9:3-5. In both these places the substance of this account is given, though not so particularly as in Matthew.

Matthew 10:9 Provide neither gold nor silver, nor brass - This prohibition of gold, silver, and brass is designed to prevent their providing money for their journey.

Matthew 10:10”

“10:9-10 Jesus’ disciples were to trust in God’s provision (6:11, 25-34; 7:7-11), to avoid greed that would give others the opportunity to defame the Lord’s name, and to encourage the newly formed communities to provide for their leaders’ needs (see 1 Cor 9:3-19).”

“Provide: or, Get neither: Mar 6:8; Luk 9:3, Luk 10:4, Luk 22:35; 1Cor. 9:7-27 Matthew 10:10”
