'Keep' in the Bible

But as for you, keep yourselves [away] from the things under the ban [which are to be destroyed], so that you do not covet them and take some of the things under the ban [for personal gain], and put the camp of Israel under the ban (doomed to destruction), and bring disaster upon it.

Only be very careful and diligently observe the commandment and the law which Moses the servant of the Lord has commanded you to love the Lord your God and walk in all His ways and keep His commandments and hold fast to Him and serve Him with all your heart and with all your soul [your very life].”

Be steadfast and very determined to keep and to do everything that is written in the Book of the Law of Moses, so that you do not turn aside from it to the right or the left,
