'Kept' in the Bible

Therefore have I also made you contemptible and base before all the people, according as ye have not kept my ways, but have had respect of persons in the law.

From the days of your fathers ye have turned aside from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith Jehovah of hosts. But ye say, Wherein shall we return?

Ye have said, It is vain to serve God; and what profit is it that we have kept his charge, and that we have walked mournfully before Jehovah of hosts?
