'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 been partial in the law.

Even from the days of your fathers ye are gone away from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith the LORD of hosts. But ye said, Wherein shall we return?

Ye have said, It is vain to serve God: and what profit is it that we have kept his ordinance, and that we have walked mournfully before the LORD of hosts?
