'Whenever' in the Bible

For whenever someone says, “I’m with Paul,” and another, “I’m with Apollos,” are you not unspiritual people?

If anyone is hungry, he should eat at home, so that when you gather together you will not come under judgment. And I will give instructions about the other matters whenever I come.

What then is the conclusion, brothers? Whenever you come together, each one has a psalm, a teaching, a revelation, another language, or an interpretation. All things must be done for edification.
