'Able' in the Bible

I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.

I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren?

There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.
