'Non christians' in the Bible

For what business is it of mine to judge outsiders? [i.e., non-Christians]; God judges them. But should you not judge those people who are inside? [i.e., Christians]. [So], remove the evil person from your fellowship [See Deut. 17:7].

Conduct yourself with wisdom in your interactions with outsiders (non-believers), make the most of each opportunity [treating it as something precious].

[Do these things] so that you will live in a proper way in front of outsiders [i.e., non-Christians], and not have [to depend on people for] any needs.

He must also have a good reputation among outsiders [i.e., non-Christians], or else he could fall into reproach [i.e., from worldly people] and [therefore] into the devil's trap.

Therefore, I want the younger widows to get married, have children and manage their homes, so that they do not give the enemy [i.e., non-Christians] an opportunity for speaking against [the church].

and maintain good conduct among the non-Christians, so that though they now malign you as wrongdoers, they may see your good deeds and glorify God when he appears.

For they went out, [ministering] for the sake of [Jesus'] name, without taking [any money] from Gentiles [i.e., non-Christians].
