'Secular' in the Bible

Her priests have done violence to My law and have profaned My holy things. They have made no distinction between the holy (sacred) and the profane (secular), they have not taught [people] the difference between the unclean and the clean; and they hide their eyes from My Sabbaths, and I am profaned among them.

“The remaining [strip of] 5,000 cubits in width and 25,000 in length shall be for the city’s common (secular) use, for a place in which to live and for open country. The city shall be in the midst of it.
