'Covenant' in the Bible

When the people (soldiers) came into the camp, the elders of Israel said, “Why has the Lord defeated us today before the Philistines? Let us bring the ark of the covenant of the Lord here from Shiloh, so that He may come among us and save us from the hand of our enemies.”

So the people sent word to Shiloh, and from there they carried the ark of the covenant of the Lord of hosts who sits above the cherubim; and the two sons of Eli, Hophni and Phinehas, were with the ark of the covenant of God.

So it happened that as the ark of the covenant of the Lord came into the camp, all [the people of] Israel shouted with a great shout, and the earth resounded.

Then Jonathan made a covenant with David because he loved him as himself.

Therefore show kindness to your servant, because you have brought your servant into a covenant of the Lord with you. But if there is iniquity (guilt) in me, kill me yourself; for why should you bring me to your father [to be killed]?”

So Jonathan made a covenant with the house of David. [He added,] “May the Lord require it at the hands of David’s enemies. [that is, hold them accountable for any harm they inflict on David].”

So the two of them made a covenant before the Lord; and David stayed [in the woods] at Horesh and Jonathan went to his house.
