'Covenant' in the Bible

But during the seventh year of her reign, Jehoiada went out and called together the rulers of hundreds, the captains, and the guards, and assembled them together inside the LORD's Temple. He made a covenant with them, making them take an oath in the LORD's Temple, and then he revealed the king's son to them.

Then Jehoiada entered into a covenant with the LORD, the king, and the people, that they would live as the LORD's people, and also entered into a covenant with the king and the people.

but the LORD showed grace to them, displayed his compassion toward them, and turned to them due to his covenant with Abraham, Isaac, and Jacob. He would not destroy them or evict them from his presence up until that time.

They rejected the LORD's statutes, the covenant that he had made with their ancestors, and his warnings that he gave them. They pursued meaninglessness and became meaningless themselves as they followed the lifestyles of the nations that surrounded them, a practice that the LORD had warned them not to do.

and with whom the LORD had made a covenant when he gave these orders to them:

You are not to forget the covenant that I've made with you, and you are not to fear other gods.

because they would not obey the voice of the LORD their God. Instead, they transgressed his covenant, including everything that Moses, the servant of the LORD, had commanded, by neither listening nor putting what he had commanded into practice.

The king went up to the LORD's Temple, accompanied by all the men of Judah, everyone who lived in Jerusalem, the priests, the prophets, and everyone including those who were unimportant and those who were important and he read to them everything written in the Book of the Covenant that had been discovered in the LORD's Temple.

The king stood beside a pillar and made a covenant in the presence of the LORD: to follow after the LORD, to keep his commandments, his testimonies, and his statutes with all of his heart and soul, and to carry out what was written in the covenant contained in the book. All the people consented to enter into the covenant.

After this, the king commanded all of the people, "Celebrate the Passover to the LORD your God, just as it's prescribed in this Book of the Covenant."
