'Idle' in the Bible

For it is not an idle word for you; indeed it is your life. And by this word you will prolong your days in the land, which you are about to cross the Jordan to possess.”

Laziness casts into a deep sleep,And an idle man will suffer hunger.

in the day that the watchmen of the house tremble, and mighty men stoop, the grinding ones stand idle because they are few, and those who look through windows grow dim;

We have heard of the pride of Moab, an excessive pride;Even of his arrogance, pride, and fury;His idle boasts are false.

“I know his fury,” declares the Lord,“But it is futile;His idle boasts have accomplished nothing.
