'Sworn' in the Bible

The Lord of Hosts has sworn:As I have purposed, so it will be;as I have planned it, so it will happen.

By Myself I have sworn;Truth has gone from My mouth,a word that will not be revoked:Every knee will bow to Me,every tongue will swear allegiance.

“For this is like the days of Noah to Me:when I swore that the waters of Noahwould never flood the earth again,so I have sworn that I will not be angry with youor rebuke you.

The Lord has sworn with His right handand His strong arm:I will no longer give your grainto your enemies for food,and foreigners will not drink your new wineyou have labored for.
