'Covenant' in the Bible

As for thee also, by the blood of thy covenant I have sent forth thy prisoners out of the pit wherein is no water.

And I took my staff, even Beauty, and cut it asunder, that I might break my covenant which I had made with all the people.

So the covenant was broken on that day, and thus the most wretched of the flock who were watching me realized that it was the word of the Lord.

Then I cut the second staff "Binders" in two in order to annul the covenant of brotherhood between Judah and Israel.
