'Oath' in the Bible

“When the Lord heard your words, He grew angry and swore an oath:

He will not leave you, destroy you, or forget the covenant with your fathers that He swore to them by oath, because the Lord your God is a compassionate God.

But because the Lord loved you and kept the oath He swore to your fathers, He brought you out with a strong hand and redeemed you from the place of slavery, from the power of Pharaoh king of Egypt.

so that you may enter into the covenant of the Lord your God, which He is making with you today, so that you may enter into His oath

I am making this covenant and this oath not only with you,

When someone hears the words of this oath, he may consider himself exempt, thinking, ‘I will have peace even though I follow my own stubborn heart.’ This will lead to the destruction of the well-watered land as well as the dry land.
