'Effort' in the Bible

They die suddenly in the middle of the night;people shudder, then pass away.Even the mighty are removed without effort.

Better one handful with restthan two handfuls with effort and a pursuit of the wind.

It has frustrated every effort;its thick rust will not come off.Into the fire with its rust!

As soon as the king heard this, he was very displeased; he set his mind on rescuing Daniel and made every effort until sundown to deliver him.
