You are starting to get a handle on the most common vocabulary in the New Testament. The flash cards for chapter 2 included 59 words. The most common words in chapter 3 involve mostly these same 59 words, with the addition of just 8 more.
So this will be the last chapter for which I supply chapter-specific flash cards. It will be hardly worth the effort to extract words used more than 3 times in chapter 4, since you will by that time already know most of them.
As with the chapter 2 cards, these can either be randomly shuffled, so you will see them in a different order each time you start...
...OR you can view them by frequency, with the most commonly used word (καί) coming first, and all the words used only three times coming at the bottom.
The meanings given to each word are not necessarily (or even, not likely) to be the way you translate the word in the context of Acts 2. These meanings (called 'glosses') are simple, one or two word phrases to trigger your memory about the word.
As you well know from looking at the LSJ lexicon, every word has a semantic range...a range of possible meanings, any one of which the biblical writer may have chosen to use.
These glosses, however, will get you started on sight-reading of the text. Once you get done with your first-pass translation, you will naturally go back and revise your translation based on your reading of the context of each word in the verse.
