'Unable' in the Bible
And it shall come to pass when it is seen that Moab is weary upon the high places that he shall come to his sanctuary to pray, but he shall be unable to.
And in the morning, It will be foul weather today, for the heaven has an aurora and is cloudy. O ye hypocrites, ye know how to make decisions based on the face of the heaven, and regarding the signs of the times are ye unable?
Now I would not have you ignorant, brethren, that many times I purposed to come unto you (but up until now I have been unable) that I might have some fruit among you also, even as among other Gentiles.
