The last two Greek words in this verse, meaning "and they," very likely belong to the beginning of the next verse. They are translated as "likewise" in the KJV, and "of them," which is the wrong form of the pronoun, and "also" in the NIV. All the translators what this "and/also" to be part of the "received" clause, but if it was it would give away the punchline, which the listeners expect to be different than the previous verse, (like theworkers) but isn't. If these words are moved to where they belong, this verse ends on the same punchline as the previous verse, "from top to bottom a denarius."
Again, all biblical translations get the preposition at the end wrong, translating it as "each" and "every." While this conveys some of its meaning, it confusing it with the very common word that Jesus uses for "each" and "every." More importantly, it destroys Jesus's play on words, emphasizing the "top to bottom" sense of the words "first to last" nouns, which can also mean "top to bottom." This preposition is only used six times by Jesus with the intent purpose of showing the range of something, here, the range of the payment.
