'Able' in the Bible

And I said to them, We have given whatever we were able to give, to make our brothers the Jews free, who were servants and prisoners of the nations: and would you now give up your brothers for a price, and are they to become our property? Then they said nothing, answering not a word.

And Ezra the priest put the law before the meeting of the people, before the men and women and all those who were able to take it in, on the first day of the seventh month.

He was reading it in the wide place in front of the water-doorway, from early morning till the middle of the day, in the hearing of all those men and women whose minds were able to take it in; and the ears of all the people were open to the book of the law.

And they gave out the words of the book the law of God, clearly, and gave the sense of it, so that their minds were able to take it in.
