'Keep My Covenant' in the Bible

Further, God said to Abraham, “As for you [your part of the agreement], you shall keep and faithfully obey [the terms of] My covenant, you and your descendants after you throughout their generations.

Now therefore, if you will in fact obey My voice and keep My covenant (agreement), then you shall be My own special possession and treasure from among all peoples [of the world], for all the earth is Mine;

“If your children will keep My covenantAnd My testimony which I will teach them,Their children also shall sit upon your throne forever.”
