'Mutual' in the Bible

Then God said, “Behold, I am going to make a covenant. Before all your people I will do wondrous works (miracles) such as have not been created or produced in all the earth nor among any of the nations; and all the people among whom you live shall see the working of the Lord, for it is a fearful and awesome thing that I am going to do with you.

Watch yourself so that you do not make a covenant (solemn agreement, treaty) with the inhabitants of the land into which you are going, or it will become a [dangerous] trap among you.

Yet let no one find fault, nor let any rebuke [others];For your people are like those who contend with the priest.
