Note 2 at Mt. 17:27: This was quite a miracle. Not only was the money supplied for their taxes, but also, it was the exact amount needed (compare with ref. c at Mt. 17:24, p. 214 and ref. n at Mt. 17:27, p. 214), and was from the first fish that was caught.

Although this sets the precedent that God can supply our needs in a miraculous way, it's important to remember that God doesn't counterfeit money. He didn't create money in the fish but rather had the fish miraculously find and swallow the exact Roman coin that Peter needed. It's a mistake to just pray and then wait on God to rain the money down from heaven. As Luke 6:38 says, God uses men (and sometimes fish) to give finances to us. He can do it in a very unexpected, supernatural way but it will involve people and existing currency. There is a scriptural precedent for God multiplying natural resources (1 Ki. 17:12-16; 2 Ki. 4:2- 7,42-44; Mt. 14:15-21; 15:32-38; Mk. 6:33-44; 8:1-9; Lk. 9:11-17; Jn. 6:5-14) but not money (see note 3 at Jn. 6:9, p. 175)
