'Able' in the Bible

and they shall cover the surface of the earth, so that one won't be able to see the earth. They shall eat the residue of that which has escaped, which remains to you from the hail, and shall eat every tree which grows for you out of the field.

You will surely wear away, both you, and this people that is with you; for the thing is too heavy for you. You are not able to perform it yourself alone.

Moreover you shall provide out of all the people able men, such as fear God: men of truth, hating unjust gain; and place such over them, to be rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens.

If you will do this thing, and God commands you so, then you will be able to endure, and all of these people also will go to their place in peace."

Moses chose able men out of all Israel, and made them heads over the people, rulers of thousands, rulers of hundreds, rulers of fifties, and rulers of tens.

Moses wasn't able to enter into the Tent of Meeting, because the cloud stayed on it, and Yahweh's glory filled the tabernacle.
