'Law' in the Bible

My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.

Set the trumpet to thy mouth. He shall come as an eagle against the house of the LORD, because they have transgressed my covenant, and trespassed against my law.

I have written to him the great things of my law, but they were counted as a strange thing.
