'Sworn' in the Bible

Yahweh of hosts has sworn, saying, "{Surely} just as I have intended, so it shall be. And just as I have planned, it shall stand:

I have sworn by myself; a word that shall not return has gone forth from my mouth [in] righteousness: 'Every knee shall kneel down to me; every tongue shall swear.'

Yahweh has sworn by his right hand, and by {his mighty arm}, "Surely I will never again give your grain [as] food to {your enemies}, and surely {foreigners} shall not drink your new wine at which you have labored."
