'Able' in the Bible

“Is not Calno [conquered] like Carchemish [on the Euphrates]?Is not Hamath [subdued] like Arpad [her neighbor]?Is not Samaria [in Israel] like Damascus [in Aram]?

Shall I not do to Jerusalem and her imagesJust as I have done to Samaria and her idols?” [declares Assyria].

So now, exchange pledges with my master the king of Assyria and I will give you two thousand horses, if you are able on your part to put riders on them.

This is what the king says, ‘Do not let Hezekiah deceive you, for he will not be able to rescue you;

“Your nakedness will be uncovered,Your shame will also be exposed;I will take vengeance and will spare no man.”

“Therefore disaster will come on you;You will not know how to make it disappear [with your magic].And disaster will fall on youFor which you cannot atone [with all your offerings to your gods];And destruction about which you do not knowWill come on you suddenly.

“Persist, then, [Babylon] in your enchantmentsAnd your many sorceriesWith which you have labored from your youth;Perhaps you will be able to profit [from them],Perhaps you may prevail and cause trembling.

O Lord, why do You cause us to stray from Your waysAnd harden our heart from fearing You [with reverence and awe]?Return for Your servants’ sake, the tribes of Your heritage.
