'Able' in the Bible

And there are men who have been defiled by the body of a man, and they have not been able to prepare the passover on that day, and they come near before Moses, and before Aaron, on that day,

I am not able -- I alone -- to bear all this people, for it is too heavy for me;

And Caleb stilleth the people concerning Moses, and saith, 'Let us certainly go up -- and we have possessed it; for we are thoroughly able for it.'

And the men who have gone up with him said, 'We are not able to go up against the people, for it is stronger than we;'

Lo, the people that is coming out from Egypt and covereth the eye of the land, -- now come, pierce it for me; it may be I am able to fight against it, and have cast it out;'

And Balaam answereth and saith unto the servants of Balak, 'If Balak doth give to me the fulness of his house of silver and gold, I am not able to pass over the command of Jehovah my God, to do a little or a great thing;

and Balak saith unto Balaam, 'Did I not diligently sent unto thee to call for thee? why didst thou not come unto me? am I not truly able to honour thee?'

And Balaam saith unto Balak, 'Lo, I have come unto thee; now -- am I at all able to speak anything? the word which God setteth in my mouth -- it I do speak.'

If Balak doth give to me the fulness of his house of silver and gold, I am not able to pass over the command of Jehovah, to do good or evil of mine own heart -- that which Jehovah speaketh -- it I speak?
