'Customs' in the Bible

(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

They are publicly teaching customs which are unlawful for us, as Romans, to accept or observe.”

Now they have been told about you, that you are teaching all the Jews who are living among the Gentiles to turn away from [the Law of] Moses, advising them not to circumcise their children or to live according to the [Mosaic] customs.

especially because you are an expert [fully knowledgeable, experienced and unusually conversant] in all the Jewish customs and controversial issues; therefore, I beg you to listen to me patiently.

Three days later he called together the leaders of the Jews; and when they had gathered, he said to them, “Kinsmen, though I have done nothing against our people or against the customs of our fathers, yet I was turned over as a prisoner from Jerusalem into the hands of the Romans.

And do not be conformed to this world [any longer with its superficial values and customs], but be transformed and progressively changed [as you mature spiritually] by the renewing of your mind [focusing on godly values and ethical attitudes], so that you may prove [for yourselves] what the will of God is, that which is good and acceptable and perfect [in His plan and purpose for you].

Judge for yourselves; is it proper for a woman to offer prayer to God [publicly] with her head uncovered?
