'Law' in the Bible

I am not saying these [things] according to a human perspective. Or does the law not also say these [things]?

For in the law of Moses it is written, "You must not muzzle an ox [while it] is threshing." It is not about oxen God is concerned, is it?

I have become like a Jew to the Jews, in order that I may gain the Jews. To those under the law [I became] as under the law ([although I] myself am not under the law) in order that I may gain those under the law.

To those outside the law [I became] as outside the law ([although I] am not outside the law of God, but subject to the law of Christ) in order that I may gain those outside the law.

In the law it is written: "By those who speak a foreign language and by the lips of others I will speak to this people, and not even in this way will they obey me," says the Lord.

the women must be silent in the churches, for it is not permitted for them to speak, but they must be in submission, just as the law also says.

Now the sting of death [is] sin, and the power of sin [is] the law.
