'Certain' in the Bible

But there were certain men who were [ceremonially] unclean because of [touching] the dead body of a man, so they could not observe the Passover on that day; so they came before Moses and Aaron that same day.

and they put him in custody, because it had not been explained [by God] what should be done to him.

and they rose up [in rebellion] before Moses, together with some of the Israelites, two hundred and fifty leaders of the congregation chosen in the assembly, men of distinction.

“But ships shall come from the coast of Kittim,And shall afflict Asshur (Assyria) and Eber;So they (the victors) also will come to destruction.”
