Good News Bible joins this verse to the previous one as one long sentence. We suggest following Revised Standard Version in keeping it as a separate sentence.

He reported to him that the treasury in Jerusalem was full of untold sums of money, so that the amount of the funds could not be reckoned: In this context the treasury in Jerusalem refers to “the Temple treasury” (Good News Bible). Full of untold sums of money and the amount of the funds could not be reckoned may be combined by rendering the first half of this verse as “He told him that the Temple treasury in Jerusalem contained so much money that it could not be counted.” Another possible model is “He told him that there were vast amounts of money in the Temple treasury in Jerusalem. It was so much that nobody knew how much was there.” For languages that prefer direct speech here, translators may say “He said, ‘There is more money in the Temple treasury [or, the place in the Temple where they store money] than we can count.’”

And that they did not belong to the account of the sacrifices, but that it was possible for them to fall under the control of the king: The legal situation described here is not clear, but probably at the root of it is the idea that once property had been given over to the Temple in place of sacrificial animals, that money, like the animals, became the property of the Temple and could not be returned. Here the assumption seems to be that the Syrian king must respect the sanctity of the Temple, and not take for his own use money that had been so dedicated. However, Simon reported that there was a lot of money in the Temple treasury that was not there for that reason, so the king could confiscate it without technically violating a holy site. An alternative model for the last half of this verse is “He claimed that a lot of this money had not been set aside for the sacrifices [or, to pay for the sacrifices], so the king could take it for himself [or, for the royal treasury].”
