'Keep' in the Bible

And hereby we do know that we know him, if we keep his commandments.

And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.

By this we know that we love the children of God, when we love God, and keep his commandments.

For this is the love of God, that we keep his commandments: and his commandments are not grievous.

Little children, keep yourselves from idols. Amen.
